201039_01

14/03/02
========
Update call ownership handling to be in line with the core etel api document
and the server document.

14/12/01
========
Defect fix to the EFaxTest code, to prevent the Phase E Hangup error -134 from being
construed incorrectly as an error and failed test case.

21/11/01
========
Fixed defect TRN-54JEDN, related to not forcing a CObjectCon add when adding a new object.
It now checks to see if the object is already in the CObjectCon list.  This is required for
TSYs that pre-allocate a pool of call objects.

13/11/01
========
Fixed some trivial CW warnings.  Left the more tricky ones (4 in each build of ETel.DLL)
until we've got more time to ensure the correct solution.

07/11/01
========

Removed GSMBAS and HAYES from ETEL component. 
This includes removal of all source code, documentation and test code
Reason is that GSMBAS is now replaced by ETELMM and HAYES is a redundant TSY that is replaced
by MMTY


26/10/01
========
Fixed defect SIH-53EM6P: In et_core.cpp (lines 1221-1248), this request has now been made just 
"multiple completion enabled" and not flow controlled.  This means TSY should have the 
phone capabilities ready to return synchronously to the client when the GetCaps request is 
received.

02/10/01
========
Fixed defect DOE-4Z6C6Y: Provide an API for ETel clients to know how many clients in total have an handle open on a call object
Created TInt RCall::ReferenceCount()

17/09/01
========
1. Added RTelSubSessionBase::CancelAsyncReq to enable extension API classes to use
this to cancel an asynchronous request rather than define a lot of xxCancel methods

2. Moved ETel heap and stack size definitions into new etelsize.h header

11/09/01
========
Fixed defect  DOE-4ZSJEU: Display "New log" in the setel logfile.

16/08/01
========
Fixed defect  DOE-4ZNE66: ETel now allows zero length callnames in OpenExistingCall.

07/08/01
========
Fixed defect HED-4VQHUC: ETel now uses Flogger for logging rather than fileserver.

23/07/01
========
1. Fixed defect SHY-4VMNAY raised in 6.1 Defects database. If a global chunk already 
exists, we now have an additional call to the OpenGlobal method to open a handle to 
the global chunk (access has been set to Read/Write). This fix has been implemented in 
RFax::TProgress* CCallBase::CreateFaxProgressChunk(). Affected file: et_core.cpp.

2. Turned the echo off in the method CFaxModem::HangupProcedureL(). Fixes defect
PBN-4TZLX7 raised in 6.1 Defects database. Affected file Cfaxmodm.cpp. This fix 
enables sms' to be read after an incoming fax has been received.

15/06/01
========
1) Increased the ECM timer to 2 min. This fixes defect SEC-4X3BY5. 
   Affected file: cfaxmdrv.cpp.

01/06/01
========
1) Updated Efaxtest.CPP file to use the new V6.2 CommDb structure.

30/04/01
========
Added code to increase the timers when receiving a fax page if the reception is using
ECM. This fixes defect EDNHKAO-4VGFG4. Affected file: cfaxmdrv.cpp.

04/04/01
========
Add multiple inclusion prevention macro and symbian boilerplating at the top of exterror.h

29/03/01
========
Fixed Fax Server defect that occured during some cancelling conditions.  The Fax Server
"logon" to the TSY thread was creating a stray signal event in the ETel Server thread
under some close down scenarios.  The cancel functionality has been modified so that
it does not terminate the thread.  Only a Close will terminate the Fax Server thread and
consume the death event.


30/01/01
========
1) Changed Fax Class 2 and Class 2.0 "hang-up status" timer from 5s to 20s. Delays for
   the "+FHS" and "+FHNG" hang-up status report message in GSM typically range from
   4s-10s.  This fixes defect EDNHMAN-4SZEBW (V3 Defects Database - migration to mainline).
2) Added code to increase the timers during Phase C by 60 seconds if the reception is
   using ECM.  This fixes defect EDNHKAO-4R6A7H (V3 Defects Database - migration to
   mainline).

10/01/01
========
1) Modifed UID3 and rearranged the ordinals of GSMBAS.DLL in order to break BC, but keep SC.
   Required due to public exposure of ETel Basic GSM API in early SDKs.

08/01/01
========
Corrected Fax Server function names, so that all functions that leave have a 'L' prepended,
as per Symbian Coding Standards.  Fixes defect CLE-4RGNHG (V4 Defects Database).

05/01/01
========
1) Added code to check for "NO CARRIER" response from modem that might be received in ECM
   mode, in Fax Class 2.0, at the start of phase D data (\ETel\FaxSvr\CFax20.cpp).  This
   fixes defect EDNHMAN-4RYJBC (V3 Defects Database - migration to mainline).
2) Added two new error codes to ETel.H: KErrEtelPortAlreadyLoaned and
   KErrEtelCallAlreadyActive to fix defect EDNACLE-4RGHJQ (V3 Defects Database
   - migration to mainline).

28/11/00
========
1) Added comments to \ETel\Inc\ET_ClSvr.h and \ETel\Inc\BscGsmCs.h to indicate the
   enumeration values.
2) Modified \ETel\SETel\ET_Man.cpp, CPhoneManager::LoadPhoneModuleL to stop loading and
   instanciating the phone factory class twice when load phone module is called twice (with
   the same TSY).  Updated the TETel test code to check.
3) Corrected problem in the MakeIni test program where the Ir Mobile phone settings where
   using the "office" location rather than the "mobile" location.
4) Propagated the defect in the GSM TSY where the buffer created to handle initialisation
   strings was not bug enough to cope with some longer strings.

06/09/00
========
Bugfix for EDNPTUN-4NJE2W and EDNHKLN-4LCBK4.
RTimer is now Close()'d in RTelServer::Connect()
(only occurred in WINS)

18/05/00
========
1) Removed over-aggressive ASSERT from CPhoneBase::CancelService, defect EDNATHE-4KEFZZ.
2) Removed over-aggressive Panic on zero length phone numbers in ETel Core API, defect EDNATHE-4JYM9R.

03/05/00
========
Fixed defect EDNGLAY-4HTCXF - Fax component will now work with no chargecard settings

02/05/00
========
Added conditional compilation to the Hayes TSY - if NO_HAYESTSY_IN_ROM is defined,
the Hayes TSY won't appear in the ROM

13/04/00
========

Added a reserved virtual function and TAny pointer to CPhoneFactoryBase and CTelObject to
assist with future BC.

22/03/00
========
1. EDNMSWN-4HLJNH, EDNMSWN-4HMELU and EDNKSHY-4HGF22 fixed 
- CreateNarrowBufferLC and CreateUnicodeBufferLC in et_phone.cpp changed so that modified (word-aligned) aSize1 and aSize2 parameters are not used for client descriptor size.  
Also the use of TDes::Right() is now TDes::Mid()
Also the aSize1, aSize2 parameters are passed by reference now rather than by value.

2. Removed inclusion of D32SND.H from ETEL. This header file is becoming obsolete.

3. Change request ACLE-4H6DL9 
Changed KShortNetworkNameSize from 8 to 20 and KLongNetworkNameSize from 16 to 30


13/03/00
========
1) Fixed integer arithmetic rounding bug in line 392 of FaxSvr\CFax1.cpp.  See source for
more details.

2) Removed UserHal::ResetAutoSwitchOffTimer() as per EDNJHAS-4GWRH9.

3) Tidied existing documentation, adding 2 fax docs.  Removed some dangerously outdated
documentation.


Version 606
===========

1) Clarified RTelServer::EnumeratePhones() by changing parameter name from aIndex to 
aNoOfPhones.

2) ETel server can now cope with TSYs which contain phones of the same name. If,say, two
TSYs both contain at least one phone with identical names the server will allow both TSYs to 
be loaded, and when RTelServer::GetPhoneInfo() is called the phone name of the phone in the
second TSY will be altered. The server ensures this name is always mapped to the correct
phone.

This means that clients should never hardcode phonenames if there is a possibility of an
alternative TSY being introduced into the system, since that TSY may contain a phone with
an identical name and if loaded first, the wrong phone will be opened.

Use of RTelServer::GetTsyName() by phone index will serve to ensure the correct phone is
opened since the TSY name which each phone belongs to can be checked.

3) Revised the future-proofing up/down calls between server and TSY. These are now

IMPORT_C virtual TInt CTelObject::UpCallOption(const TInt aOptionNumber, TAny* aData);

and 

virtual TInt CTelObject::DownCallOption(const TInt aOptionNumber, TAny* aData);

The TSY should overload the DownCallOption() if required. The server will implement
UpCallOption() if required.

4) Merged in bug fixes from EPOC5u - (a) the cancelling of CGsmPhoneBookSearch and 
CBasicGsmRetrieveDetectedNetworks operation,
				(b) the value of KErrEtelGsmBase is now -4000.

Version 605
===========

Changes to test code.

Version 604
===========

Released on src_epoc, built against mainline baseline 00029

Defect fix for the value of KErrEtelGsmBase ( it was -3000, it is now -4000 ) - as it
clashed with the NETDIAL error definitions

Tested with TGSM under WINS UDEB


Version 602
===========

This release re-adds those exported functions that broke the mainline build when they 
were removed in 601 (see point 7) because ETelAgsm uses the CGsmPhoneBookSearch protected
functions. The CBasicGsmRetrieveDetectedNetwork protected functions remain un-exported.


Version 601
===========

This release is for the mainline. Breaks binary compatibility for ETel.dll and 
GsmBas.dll but maintains source compatibility for clients. Minor break in source 
compatibility for TSYs due to point 1.

1) Narrow UIDs and narrow-specific code has been removed. This has led to the removal 
of two functions from TDataPackage, Des1() and Des2(), since these were used to return
either a narrow or a unicode pointer depending on build. Now we have just Unicode builds
so these are obsolete. Des1u() and Des2u() can be used in their place.

Added ASSERTs on the remaining functions of TDataPackage to ensure the TSY does not ask for
an invalid parameter for a particular IPC. The panic will be EEtelFaultDes1DoesNotExist or
EEtelFaultDes2DoesNotExist.

2) Fixed bug reported in ER5u database: EDNDMAY-4A6HZQ - "Unnecessary use of floating point
arithmetic in ETEL". This was originally fixed in ETel 558 on ER5u share.

3) Fixed bug reported in ER5 database: EDNMSWN-4AMJ2C - "GetBearerServiceInfo returns old
information even when not connected".

4) Contains the Fax ICF, outlined in ER5 database: EDNARAO-488JRS = "Sending a fax does not
work properly", which involves minor changes in the Fax Server, ie, delaying the point at
which software flow control is switched off until after an OK has been received for Fax 
Classes 1 and 2.

5) Fixed bug reported in ER5 database: EDNAWIR-462NV8 = "ETel Server Thread function does
not check error on loading library".

6) Fixed bug reported in ER5u database: EDNMSWN-4BXHW6 - "RTelServer::Connect() uses default 
msg slots rather than client requested number". This was originally fixed in ETel 561 on 
ER5u share and has been migrated to this share.

7) Removed unnecessary protected exports from CBasicGsmRetrieveDetectedNetworks and 
CGsmPhoneBookSearch. This also fixes a bug from ER5u where the CBasicGsmRetrieveDetectedNetworks
class exported these protected functions in WINS only, because the EXPORT_C macro
had been omitted from the implementation of the functions.

Version 600
===========

This release is for the Crystal DFRD.

1.	Converted HAYES.TSY and FAXCLI.DLL and testcode to use new COMMDB.

2.	Fixed VC6 warnings.

3.	Fixed bug EDNAWIR-4ALKET in CCallHayes and CLineHayes destructors
	in HAYES.TSY.


Version 557
===========

This release is for the Crystal DFRD.

Changes are made only to the fax components of etel.

These include 
1) Support for 2D functionality
2) Support for ECM (Error Correction Mode) functionality.

The fax components FaxCLient and FaxServer are no longer binary compatible with any
previous versions due to changes to the Faxclient and FaxServer API .

The test code was also modified to provide test coverage for the new functionality.

The FaxServer API was also changes and some member data are now protected instead of public.

	f32		146

	e32utils	027
	e32tools	121
	e32toolp	109
	eiktools	133

This has been released onto the ER5u share. The last release of ETel on ER5u was 552,
and there have been binary incompatible changes since then. It is, however, BC with 555.

1) Removed Faxcli's dependancies on FaxIO and C32.

2) Updated mnt file to cope with latest MAKMAKE changes. There will still be warnings when
building,however, since DOEBLD.BAT (part of eiktools) still uses the \makework command
on MAKMAKE. These can be safely ignored.

3) Updated RComCopy.rbt. The correct files are now copied to the ARM for testing.

4) Removed narrow builds from ebld.bat and mnt.cmd, and rebuilt against FaxIO and FaxStrm
which supersede FaxStore on ER5u.

Version 555
===========

1) Fixed memory leak bug in ET_CLI.cpp. If a call to ConstructL() fails, the Destruct()
function is called to clear up any allocated memory.

2) Fixed bug in CPtrHolder::ConstructL(). The return values of RArray::Append() are now
checked, and if not KErrNone it will leave.

3) Split ET_phone.cpp into two .cpp files : ET_phone.cpp now contains CTelObject and
CSubSessionExtBase implementation, which ET_Core.cpp contains CPhoneBase, CLineBase,
CCallBase and CFaxBase definitions.

4) Added Auto-registration ability to ETel. This means that some notifications have a
hard-coded number of server-side slots associated with them, which should guarantee that
events will not be lost for any notification where it is important that they are captured.
A new pure virtual function has been added to MTelObjectTSY, NumberOfSlotsL(const TInt aIpc), 
which returns the number of slots in a notification's buffer. This is the TSY's 
responsibility. Two new header files are provided which give default standard values for 
each notification - ETBuffer.h for the Core API and ETBscBuf.h for the Basic GSM API.
The TSY can choose to use these values or not. If a notification is not mentioned in these
header files, it is because the default is one slot.

5) Fixed bug in RBasicGsmPhone::SetAlarm() client API code, which was calling 
RTelSubSessionBase::Get() instead of RTelSubSessionBase::Set().

6) Unicode fixes in Core API:

	- TTelNumberC is now a TDesC.
	- Fax AnswerBack string is now a TBuf.
	- Fax Identifier string is now a TBuf.

7) Unicode fixes in Basic GSM API:

	- The iShortName and iLongName members of class TNetworkInfo are now TBuf's.
	- TGsmPassword is now a TBuf.
	- All four members of structure MBasicGsmPhoneId::TId are now TBuf's.
	- The iText member of structure MBasicGsmPhoneClockAndAlarm::TAlarm is now a TBuf.
	- The iText member of structure RGsmPhoneBook::TEntry is now a TBuf.
	- typedef RGsmPhoneBook::TSearchString is now a TBuf.
	- The iTelNumber member of structure TGsmTelNumber is now a TBuf.

8) ETel server now allows functions to take one narrow parameter and one unicode parameter.
The modified RCall::Dial function, which now takes a Unicode dial string in the UNICODE
build, makes use of this functionality which is provided by 4 new functions at the 
RTelSubSessionBase level: 2 Get() functions and 2 Set() functions, each taking one 8-bit
and one 16-bit parameter. Synchronous and asynchronous variants are provided.

9) Removed BARRED_PHONEBOOK #definition from Basic GSM API, as it is not part of the GSM
07.07 specs. It will be added to the Advanced GSM API.

10) Added 12 to the size of TSms::TPdu, as the size of the SC address was not taken into
account.

11) Fixed bug in ETel server which prevented RCall::GetBearerServiceInfo from receiving any
updated information.

12) WINS only. Altered the timer in RTelServer::Connect() from 0.4s to 0.5s, as the 
continuous opening and closing of the server in the WINS environment was causing a panic
at random times, caused by the imperfect reproduction of the thread priorities on WINS.
(On ARM, the ETel server thread will be at higher priority than any client thread).

13) Fax Server bug fix. CFaxClass2::AnalyseFHNG() function has been removed.

14) ETel Server bug fix for requests which are both flow control obeyed and multiple 
completion. 

15) Updated SvrDesgn.Doc, CoreApi.Doc and BsGsmApi.Doc.

Version 554
===========

Same dependancies as 553.

1) Isolated tests in TETEL.EXE which leak memory client side due to testing bad client 
scenarios which do not close handles properly, and moved these out of the UHEAP_MARK
section. Ensures that if the UHEAP_MARK_END detects memory loss, it is not intentional!

2) Updated TGSM.EXE and DGSM.TSY to ensure every test runs OK in the aftermath of the
removal of specific RegisterXXX() functions.

3) Altered server/TSY interface, removing the NotifyOnAnything() functions and support for
Registration of notifications (ie the CheckAndSetRegistrationParams).

4) Made the server unicode-compliant so that the UNICODE Get() and Set() functions will
work. This has meant a non-BC change on the server-TSY interface, in that the parameters of
CTelObject::ExtFunc() has changed to

ExtFunc(const TTsyReqHandle, const TInt, const TDataPackage& )

where the class TDataPackage is defined in ET_Tsy.h. It contains the pointers to the data
associated with the function call, whether narrow or unicode, and provides the TSY with 
functions to access whichever it needs. In most cases the data is a structure which has
been packaged up into a (narrow) descriptor on the client side - for these cases the TSY
can simply call TDataPackage::Ptr1() or Ptr2() which returns a TAny* pointer that should be
cast into the relevant type. 

The functions Des1() and Des2() should be used if the client-
side function takes a TDes& parameter. In the rarer case of the client-side function taking
a TDes8, the TSY can call Des1n()/Des2n() to ensure it receives a pointer to a narrow 
descriptor. The equivalent Des1u()/Des2u() functions are added in case a client-side
function ever takes an explicit TDes16& parameter.

There is currently no way for a clientside function to pass down one narrow parameter and one
unicode parameter. This may be added in the future and should be a BC change on both
interfaces of ETel (top and bottom), but will mean a decent increase in complexity in the
server because currently both parameters are stored in the same buffer which is either
8 bit or 16 bit.

5) Tidied up Cleanup Stack errors in server. 
	(a) CTelObject::WriteBackAndCompleteReq() and 
	    CTelObject::WriteBackAndCompleteBufferedReq both called RMessage::WriteL().

	These now trap the leave.

6) In Basic GSM API, the class CGsmDetectedNetworkResults has been renamed
CGsmNetworkList and its functions genericised in order for the Advanced GSM API to make
use of it. This is a binary compatible change but not source compatible.

7) Documents CoreAPI.doc, BsGsmApi.doc and SvrDesgn.doc have been updated.

This release has been placed on the src-era share not the ER5u share because:
1) When delivered to externees, the narrow build is required.
2) The ER5u share is currently going through a transition phase.

Changes:

1) Altered the mnt.cmd and ebld.bat files back again to allow narrow builds.
2) Added TCallParamsPckg typedef to Basic API.
3) Uses Faxstore not FaxIO, since FaxIO is not on the src-era share.
4) Implemented RTelServer::GetTsyVersionNumber() - it no longer returns KErrNotSupported,
   but the version number of the TSY. This has required no change to the TSY.

Tested: All except EFaxtest.

BC with 552.

Version 552
===========

1) Added BLD.INF file.

2) Built against ER5u baseline.

3) Changed to depend on new FAXIO and FAXSTRM rather than FAXSTORE.

Version 551
===========

THIS BREAKS BINARY COMPATIBILITY WITH 550. But not source compatibility.

1) Increased stack size in Fax client from 0x1400 to 0x4000.

2) Removed NotifyOnAnything functions from Core and Basic.

3) Removed Booleans from "NotifyInfo" structures since now only used by GetInfo(),
	and renamed them to TxxxInfo from TxxxNotifyInfo.

4) Removed Text mode support from TSms, and changed KPduSize to 165 (true size without
	text structures).

5) Removed Register/Deregister functions.

6) Added GetTsyVersionNumber() to RTelServer.

No testing done as yet.


Version 550
===========

This is the first ER5u release. All narrow builds have been removed.

1) mnt gettestrel now pulls down the test TSY's (DSTD, DSTDNC, DBAD and DGSM).

2) Extended error handling functionality has been added to the server.

Version 050
===========

1) Fixed bug where it was possible for the TSY to go into an infinite loop of 
   sending ATs in while doing quick initialisation.

Version 049
===========

1) Implemented workaround for serial driver bug where the serial driver gets into a bad 
state after a comms line fail.  This is worked around by resetting the baud rate which
kicks the driver enough to make it start responding again.

Version 048
===========

SERVER:

1) Fixed bug in CTelObject::UpdateBuffer(), where if the new data were being copied from a
non-registered function to a registered function (with a multi-slot buffer) the wrong 
type of message was being looked up.

2) If TSY completes a request with KErrCancel without the cancel function being called,
the server used to give an unhandled exception, now it panics with 
EEtelFaultCancelErrorWithoutCancelled.

3) RTelSubSessionBase::TTsyKnowledge implementation was flawed in the server. It now 
forces the TSY to receive every client's request by masking out the multiple 
completion characteristic, even if the TSY sets it.

4) When a CDestroyDummySubSession object had decremented the reference count on a CTelObject
it was assuming the CTelObject was destroyed and did not tell the CTelObject to NULL its 
pointer to itself (it deletes itself as a CAsyncOneShot should). Now it does.

5) If CTelObject::CheckAndSetRegistrationParams() returned an error, there was a possibility
of the outstanding request to be registered already being asked to cancel. Some 
rearrangement was necessary to ensure that on a Registration request reaching the server
all that is done before CheckAndSetRegistrationParams() is called on the TSY is a couple of
checks are made and the data buffer is copied across to pass the parameters to the TSY.

TSY :

1) Bug report EDN551995 fixed. Dial Cancel() would not work if the Dial command had just
been written but the write hadn't completed. Answer Cancel() and Connect Cancel() similarly.

2) Increased timeout of AT+FCLASS=? query from 1 second to 2 seconds.

3) CCallHayes::RecoverDataPortAndRelinquishOwnership() now calls the correct completion
function RecoverDataPortAndRelinquishOwnershipCompleted() rather than
RelinquishOwnershipCompleted(). This means the server is now aware that the data port is
no longer loaned. NB This bug would only occur if there was another client willing to 
acquire ownership of the call.


MISC :

1) in Mnt.cmd deleted unnecessary secondary GetEalwl command.

2) "mnt putrel" was attempting to release *.map files from the ..\WINS\ directories and 
obviously failing, but without an error.

3) Updated Basic GSM API document.

Version 047
===========

Same dependancies as 046.

Only change is bug fix in Fax Server. It was reporting a file error if the \logs\fax
directory did not exist. Now it will put the log file in \system\ directory if \logs\fax
does not exist.

1) Moved definition of Fax server UID's from TSY to FaxServ.h (Fax server's exported header
file).

2) TSY now allows all handshaking to be applied when a client loans the data port. It is
then the client's responsibility to mask out any appropriate handshaking constants. This
allows TCPIP to detect a dropped carrier.

3) Split out the advanced GSM into a separate project (ETelAgsm).

4) Tidied up the MNT.CMD file.

5) Fixed TSY panic bug, where a KErrCommsFrame during Initialisation did not cause all 
the chat strings to be deleted. Report in EDN440375.

6) EBLD.BAT's "EBLD ALL" command tried to rebuild WINS again. This has been fixed.

7) FAXSVR:

Fix implemented for defect EDN654383  (application panic when canceling a fax)

Fix implemented for defect EDN832685  (a break instruction was missing from a for(;;) loop)

BC with 044, except FaxSvr.dll

1) Fixed Panic in Quick Init bug.
2) Made Fax Server dynamically loadable by a TSY, rather than statically linked, to 
speed up the load time.

Version 044

Dependancies - same as 043

Quick release to put right the source incompatible changes. All instances of Initialize
have been rewritten Initialise. Therefore, source compatible with 042 but not 043.

Binary Compatible with 042 but not source compatible.

CORE API:

1) The following functions/enums have been Americanised (from "s" to "z") :

RPhone::Initialise()
RPhone::InitialiseCancel()

MPhoneBaseTSY::ControlledInitialisation()
MPhoneBaseTSY::ControlledInitialisationCancel()

enum EEtelPhoneInitialiseCancel (in ET_ClSvr.h)

const TInt KErrEtelInitialisationFailure=KErrEtelCoreBase-6; (in ETel.h)

2) Removed KDefaultInterval from ETel.h, as unused.

3) Added RTelServer::GetTsyName(const TInt aIndexOfPhone, TDes& aTsyName) 
to core API. This allows a client to know which phone belongs to which TSY, and so can 
open the correct one.

4) New error code KErrEtelModemSettingsCorrupt = KErrEtelCoreBase-18. This is returned by 
the TSY if CommDB passes back an error when attempting to read the default settings, on
the construction of CPhoneHayes.

TSY:

1) RPhone::GetCaps() has been made synchronous on the TSY side.

2) Modified Recover Data Port sequence to be slightly quicker (by one second).

3) Checks for null pointers included in dtr's for CPhoneHayes, CHeartBeatRunner and
CTsyConfig. Fixes bug reported in EDN760205.

FAX:

1) Removed StartC32() from FaxCli and FaxSvr. ETel is not responsible for StartC32, as it
runs within the C32 process itself.

2) Altered Fax client such that it makes use of fix CORE:3 above. It now does not need to
be hardcoded to know which phone belongs in which TSY.

3) Jerry:

FaxCli

	Fixed a bug were the fax client was attempting to use the modem even if it was used by 
	someone else. This caused some panics in the messaging application. When a user was 
	connected to an e.mail account and accidentally tried to send a fax the messaging app was 
	panicing

Faxsvr
	Changes included to support the SIEMENS M1 module.
	
	The changes for the M1 support introduced a bug where the faxserver was setting the 
	compression of the fax to be sent to the compression capability supported by the modem
	not the actual compression method of the fax document. This had the effect of getting 
	transmitter stalled errors, and if the fax was sent "correctly" only the header was 
	printed at the remote machine.

	AnalyseFHNG() function added to the fax server (for class 2 only) to enhance the logging 
	capabilities. The faxlog now contains much more readable information about the possible
	causes of a failed fax session.

Binary Compatible with 041.

CORE :

1) ETel's stack size down from 40k to 8k.

2) Registration of a buffer size of 1 meant that even if the data was overwritten due to 
a slow client, the KErrOverflow error was never returned. This has been fixed in the server.

3) Server no longer calls ReqModeL() on completion of a TSY request - it stores the mode
that it determines when the client request first reaches the server.

4) Altered when the Read is posted in the I/O class to ensure the TSY never post a Read
twice before the first completes.

5) Bug fix for EDN418326. TSY now overloads various CTelObject::ReqModeL() functions, and
includes the ET_Clsvr.h file which contains the IPC numbers. This allows the TSY to 
complete all IPC's which obey flow control with KErrInUse if the data port is loaned, rather
than the server queuing it until the port is recovered.

The TSY can make a decision on what to do if a function is called which obeys flow control
because it retrieves information obtained from the initialisation, but which is synchronous
on both client and server sides, and the data port is loaned. The TSY could temporarily 
remove its ObeyFlowControl status in that case.

6) RecoverDataPort() now checks that the client is owner of the call, or a priority client.

7) CPhoneHayes::ControlledInitialise() now checks whether the Automatic Init sequence has
only just completed, and if so does not re-initialise but completes immediately with
whatever error the Init sequence completed with. This allows clients to call RPhone::
Initialise() while the TSY is auto-initialising, which will complete as soon as the modem
has been initialised. This helps to prevent the blocking of certain functions which are 
synchronous on both client and TSY sides but obey flow control because they retrieve 
information obtained during the Init sequence, so the server would queue them until it had
finished. A client may now know when it is OK to call one of these functions.

BASIC :

1) Added asynchronous and cancel variants to the following functions in the Basic Gsm API:

MBasicGsmPhoneClockAndAlarm::ReadClock()
MBasicGsmPhoneClockAndAlarm::SetClock()
MBasicGsmPhoneClockAndAlarm::EnumerateAlarm()
MBasicGsmPhoneClockAndAlarm::GetAlarm()
MBasicGsmPhoneClockAndAlarm::SetAlarm()
MBasicGsmPhoneBookSupport::GetPhoneBookInfo()

The last function's async and cancel variants used two of the free slots allocated to 
prevent BC breaking. The others were simply added, as no client is using them currently.
This has been tested to ensure BC is maintained.

2) Bug in client side Text Mode SMS code fixed.

3) Bug in RBasicGsmPhone::NotifyChangeOfNetworkSearchMode() client side code fixed. It was
passing down the wrong descriptor.

4) Moved all CBS related functionality from Basic to Advanced GSM API. This has maintained
BC by the replacing of the functions with nulled functions.

MISCELLANEOUS :

1) Mnt file environment variables tidied up.

Version 041
===========

BC maintained.

1) Added asynchronous and cancel variants to the following functions in the Basic Gsm API:

RSmsMessaging::SetMode()
RSmsMessaging::GetDefaultSCAddress()
RSmsMessaging::GetMessageStoreInfo()

2) Just tested TGSM as nothing else has changed.


Version 040
===========

Dependancies - same as 039

1) Fixed bug in TSY, handling Comms Frame error during initialisation.

2) SetFaxSettings no longer obeys flow control, as it is synchronous and therefore should
not be queued by the ETel server. This requires change to Fax client so that if it is 
called before the modem capabilities have been discovered in the initialisation sequence,
it will be re-posted.

Also a small change to CCallFaxHayes::SetFaxSettings() so that KErrEtelModemNotFound returned
if the state is not in an initialised state (ie may still be initialising.)

3) Optimised Fax client so that cancelling is quicker (don't attempt to hang up if call is
already idle).

4) Modified EBLD.BAT so that the directories \z\system\data etc are not added to
\epoc32\release\marm\xxxx.

5) Fixed callback bug EDN791409 - ETel wasn't reading the RING's on callback.

6) Fax server now looks for "NO DIAL TONE" as well as "NO DIALTONE".

7) Moved the masking out of FailDSR in Init sequence from just after the Null Write has 
completed to once the first OK has been received. This means that if the user has 
inadvertently got the cable connected to the PC rather than a modem, the error code should
be KErrEtelNoModemDetected rather than KErrCommsLineFail.

8) Documentation not quite up to date with USSD.

9) Fixed bug in waiting for a RING before proceeding with init sequence - if a RING had 
occurred but not for some time the initialisation sequence could hang as it waited to be
called back after the next one came in.

10) USSD commands moved from Basic to Advanced API, maintaining BC (this has been checked.)

11) Bug fixes made to Advanced GSM client side code, in parcelling up the data.

12) Several Advanced GSM functions modified.

Beta release. --- NO LONGER (4/2/99)

1) Modified hang up sequence - DTR low period was increased from 100 to 500 milliseconds,
and the DTR raised period was increased from 100 to 200 milliseconds. This causes the 
modem to respond with NO CARRIER to the following ATH, or +++, command.

2) Changed default value of loudspeaker control value from "Always on" to "On until Carrier",
in the default constructor of the RCall::TCallParams structure.

3) Client-side Bug fix in overloaded functions for RCall::AnswerIncomingCall() 
and RCall::Connect() which do not take the RCall::TCallParamsPckg structure - they now
just pass down a NULL descriptor to the TSY which interprets this as meaning it should
read out the call parameters from the Comms Database. RCall::Dial() did this already.

4) TSY bug fix. If a modem command sequence calculates that it cannot execute before the
next RING comes in, it waits for the RING and then begins. However, if a RING didn't come
in the sequence would not be restarted. This has been fixed.

5) RPhone::InitialiseCancel() function added. Tested to ensure BC kept.
   Initialise Cancel implemented between server and TSY.

6) RSmsStorage::Write() should take a TInt& aIndex, not a const TInt aIndex, as the value
is returned.

7) Moved CBasicPtrHolder class out of public header.

8) Fixed DTR being held high if call is dropped while data port is loaned (this seemed to 
be the problem anyway.) Looks like none of ETel's writes were completing due to handshaking;
masked it all out.

Jerry : (FAX)

Fixed a bug where the faxserver was trying to set the modem attached 
to the user settings without checking these were supported by the modem.
Now the fax works with the M1 module.

1) RelinquishOwnership now checks whether the quick initialisation sequence is running
before attempting to hang up, and cancels the sequence first if it is.

2) Moved the ownership of CATQuickInit from CCallHayes to CCallDataHayes to improve 
memory efficiency.

3) Work around for ESock thread hanging with Netdial using ETel, using IrDA. Fixed in 
the Initialisation sequence by not queueing a null read until the RPhone::Open has 
completed.

4) Work around for KErrAccessDenied error from DBMS when first reading a string using
CommsDB, on the ARM with NetDial and IrDA running (timing problem?).

5) Bug fix in initialisation sequence. If it leaves half way through with an error,
the next time it is started the queueing of a null read will not cause a comms server panic.

6) Bug fix in Notifications Handler, which was completing a call status notification
for all calls, not the one designated to answer.

7) Modified FaxCli, and Hayes.TSY, to work with Auto Fax Class.

8) Hayes TSY, if asked to wait for a RING by either NotifyIncomingCall or AnswerIncomingCall
will tickle the OS every 10 seconds until it is answered to ensure no automatic switch off
occurs.

1) RTelServer::GetPhoneInfo() now returns a value of 0 for its iExtensions member.
2) FaxCli now checks the name of the phones it gets back from all loaded TSY's, and
opens the one appropriate to the connected modem table's TSY.

3) Interface between TSY and Fax server has swapped around. Now the Fax server exports the
functions for the TSY to call, and provides an abstract base class for the TSY to implement
which holds the completion functions. This allows other TSY's apart from Hayes.TSY to use
the fax server, such as GSMBSC.TSY. NB : this means that GSMTSY version 013 and lower
will not work with this release of ETEL.

4) Logs for ETel server and Hayes TSY have been renamed to "SETEL.TXT" and "ETEL.TXT" 
respectively.

5) Resource files introduced for Hayes.TSY

6) Jerry on fax:

The efaxtest code has now an improved interface where the backspace key works as it should.
The faxserver code now includes some enhancements from the faxtrans code which were not 
implemented in the faxserver code. See bug report EDN094835 for details.

Changed efaxtest mmp file because of a stack overflow problems in the wins Unicode Debug version.

Faxserver code has a new public header file (faxserv.h). The problem was that the faxserver could use only the 
Hayes.tsy, and was not aware of the existence of gsm.tsy. So the depedencies ware swapped around and now any client
(tsy) can use the faxserver. This dictated changes in the public interface (exported functions) so this 
version of faxserver is not binary compatible with previous versions (sorry ;-)).
Changes to the faxserver.mmp file were also made, as some depedencies were removed.
the same applies for the faxcli.mmp file.

Fixed a bug in the faxserver where if state was returning with -137 (WrongModemType) an exception was raised.
Fixed bug EDN094835 were a faxsession could go on indefinitely if the receiver hang up. Now the faxsession ends 
after thee failed attempts.
Fixed a bug where a fax file with not supported compression (or corrupted) could cause an exception under wins.

7) Added RAdvGsmLine::GetCallInfoAdvGsm(const TInt aIndex,RAdvGsmCall::TCallNotifyInfo)
to the advanced GSM API, into the MAdvGsmLineStatusAndCallInfo mixin (formerly known as
MAdvGsmLineStatus).

====
CORE
====

1) During Pre-Connection initialisation, if a RING has just occurred then a timeout of 
half a second is completed before continuing, to ensure modem is in a ready state.

2) Fixed a Relinquish Ownership bug in the TSY.

3) FailDCD handshaking masked out during connection, as a NO CARRIER message is far
   stabler to cope with than a KErrCommsLineFail error from the comms server.

4) Fixed AT+FCLASS=0 bug.

5) ETel server now moves all TSY names to upper case, rendering the LoadPhoneModule()
case insensitive.

6) TSY no longer checks the TSY name in the default connected modem table in the Comms
database against its own name. It is valid for 2 TSY's to be simultaneously loaded in 
which case 1 or neither of the TSY's will have the database specified name.

7) TSY now will not allow a phone to be opened if some other TSY already has a phone 
opened.

FAX:

8) fixed a bug in the wins deb variant which could cause an unhandled exception if 
state returned -137 (WrongModemType).

9) In EFaxtest, the fax test code:

Returns error messages instead of error codes.
the backspace key now works so the entry can be edited.
There is no need for the user to type t before the telephone number.

10) Changed string in CFAXMODM.cpp to update the string printed in the faxlogs.

11) FaxCli, the fax client DLL, now queries the TSY for the name of the phone to open,
rather than the hardcoded "Phone1".

=====
BASIC
=====

1) Changed name of member data iTypeOfAddress in structure TGsmTelNumber to iTypeOfNumber.

2) Changed name of RGsmPhoneBook::AddressChangedNotification() to EntryChangedNotification().

3) Changed name of CGsmDetectedNetworkResults to CGsmNetworkResults so it can be used by 
both Retrieving Detected Networks and (Advanced) Retrieving Preferred Networks

===
ADV
===

1) Changed MAdvGsmLineBarring::BarringModeNotification(TRequestStatus& aStatus,
TBarringType& aType, TBarringSetting& aSetting) to take TBarringMode instead of 
TBarringSetting.

2) Moved SIM capabilities from line level to phone level.

3) Advanced phone book search now takes type TSearchVariety which contains both search
type (basic text, wildcard text or number) and order (by index or alphanumerical).

4) Get and Set Preferred Network Info now uses MAdvGsmPhoneNetwork::TAdvNetworkInfo instead
of RBasicGsmPhone::TBscNetworkId. The new structure includes the latter plus the short and
long name of the network. The Master List network info uses the same structure, thus
eliminating the need for TStaticNetworkInfo. The storage class CGsmPreferredNetworkResults
is also obsolete as the re-named CGsmStaticNetworkResults class (to CAdvGsmNetworkResults)
now holds MAdvGsmPhoneNetwork::TAdvNetworkInfo objects.

5) DTMF phase entered and left notifications have been replaced with one notification,
MAdvGsmCallDTMF::NotifyDTMFEvent() which returns whether the event is entering or leaving
DTMF, and whether it was automatically started or manually.

6) MAdvGsmCallDTMF::StartDTMFTone() and MAdvGsmCallDTMF::StopDTMFTone() functions added.
This allows the client to deal with a user pressing a key on the keypad and actually 
sending that tone while the key is depressed.

7) Moved SetAocMode and GetAocMode from call level to phone level. AOC cannot be enabled and
disabled on a per call basis, indeed it cannot be enabled or disabled at the network 
side at all. All this should do is tell the TSY or signalling stack that it should not
propagate AOC information upwards. The question is whether we need it at all if clients
can request it when they need it.

Maintains Binaray Compatibility.

1) Pace Microlin Surfer was not answering properly during PPP callback. Problem fixed in 
Hayes TSY by lowering and raising DTR if "NO CARRIER" is discovered when data port is 
recovered.

2) Initialisation with IR modem - the first write may take a while to complete. So
timeout has been increased from 1 second to 5 seconds.

3) Nokia 9000i does not accept values greater than 2 for the speaker control command "ATM",
although 3 is usually a valid command. So TSY now ignores an ERROR coming back from this 
set command.

4) Re-initialisation bug in TSY, where another Read was not posted, has been fixed in the
CATIO::Read() function, which now checks whether a Read is pending and does not queue 
another if it is. This allows the rest of the TSY to queue a Read even if it's not clear 
whether one has been queued already.

5) The last release of ETel had an unintentional break of BC in GSMBAS.DLL for which a 
fix was posted. This fix is now incorporated into this release. The problem was that with
RGsmPhoneBook::AddressAddedNotification and RGsmPhoneBook::AddressRemovedNotification being
replaced by AddressChangedNotification, the IPC's for these requests were removed - thus
changing the values of all the later enumerated IPC's. The IPC's have been replaced but
are now dummy values.

6) The "Own Number" phonebook name definition in ETelBGsm.h has been removed as this
functionality really belongs in the Advanced Phone.

2) Logs (ETEL.LOG and SETEL.LOG) now written to c:\logs\etel\ if it exists.
3) Implemented EBLD maintenance batch file.
4) Converted to LITERAL descriptors where appropriate.
5) Fixed TSY bug where Callback was causing it to panic.
6) Fixed ETel advanced client-side bug in RAdvGsmLine::NotifyGsmStatusChange().
7) Fax client FaxCli.dll now reads the Comms database to discover the current TSY to 
load up, rather than the hardcoded Hayes.TSY.
8) Previously, when a RING was detected by the TSY and no call had had AnswerIncomingCall()
called on it, the TSY automatically "created" a data call from its Pre-Allocated Call and
let the client know its name using a RLine::NotifyIncomingCall() or a RLine::NewCallAdded().
There is no way of knowing whether the incoming call is data or fax on a terrestrial modem
so the TSY chose data by default.

Problem: A client calling RLine::NotifyIncomingCall() on a fax line will not be notified
because the TSY has made up its mind it is a data call.

Soln: Once a RING occurs, and no call has had AnswerIncomingCall() called on it, the TSY
will check which line has had NotifyIncomingCall() placed on it. If just the fax line, the
TSY will create just a fax call - similarly for data. If both have been placed, the TSY 
will create both and then the client with the highest priority will answer first. If neither
notification is placed the same will happen.

9) As a caveat of (8), the NotifyIncomingCall request no longer has the 
KReqModeRePostImmediately capability (assigned by the ETel Server), as this reduces the
possibility of having NotifyIncomingCall outstanding on both lines which would result in the
less desirable situation of having two calls created when the modem rings.

10) Advanced GSM API. Altered functions 
(i)MAdvPhoneLineIdentity::ColpModeNotification()
to take the parameter TColpMode instead of TColpSetting (allowing the return value of 
EColpModeUnknown), and

(ii)MAdvPhoneLineIdentity::ClirModeNotification()
to take the parameter TClirMode instead of TClirSetting (allowing the return value of
EClirModeUnknown)

11) Basic GSM API. Added Reset() functions to both CGsmDetectedNetworkResults 
and CGsmPhoneBookResults. This allows a client to clear all results from the class 
and reuse it.

12) Fixed client-side bug in async version of RAdvGsmPhone::SetPreferredNetworkInfo().

Documentation not up to date in this release.

Core is binary compatible on the client side, but not on the TSY side. So the Hayes.TSY
(part of this project) has been modified to build against it, and GSMTSY (separate project)
must be rebuilt against it.

Both the Basic and the Advanced GSM DLL's have unavoidably had to break BC.

CORE
====
1) CTelObject::ArrayOfMemberDataSizes() now passes the IPC of the request.

2) Problem : The CallParams structure passed down with Dial(), Answer() or Connect() is set to 
default if constructed with default c'tr, and not default if constructed with copy c'tr.
The TSY checks the default member and if set to true pulls out the information from Comm DB,
otherwise it uses the information in the structure. However, if the client creates the
CallParams structure prior to its member data being filled in, the default will still be set
to true.

 Fix : Hayes.TSY no longer checks the default member. If the Dial() function without the
CallParams structure as a parameter is used, the packaged descriptor is set to zero length
which tells the TSY to use Comm DB. Otherwise, the overloaded Dial() function with CallParams
structure being called, whatever information is in the CallParams structure will be used
by the TSY.

3) FaxCli now no longer passes down the call params structure with Dial/Answer/Connect,
using the overloaded functions which don't take it as a parameter. The Hayes.TSY pulls the
values out of Comm DB.

4) Ownership of a call is now on session-level, not sub-session. 


GSM
===
1) Added Advanced Phone mixin for the phone's static and SIM capabilities.
2) Added Advance Line mixin for line-level SIM capabilities. SIM capabilities are caused
   by the Customer Service Profile information on the SIM.
3) Basic Gsm - phone book address added and removed notifications have been replaced by
	a changed notification.
4) RGsmPhoneBook::GetInfo() now returns the more complete structure scoped in RBasicGsmPhone.
5) Basic Network functions have been enhanced - see below.

6) SetNetwork() split into two functions - SetNetworkMode(), which uses the last current
   network ID if Manual is selected, and - SetManualNetwork(), which selects a particular
   network by ID, manually.

7) Additional functions in Basic Phone Network, for retrieving Network Registration status
	and search mode. Corresponding member data added to TPhoneNotifyInfo.

8) RBasicGsmPhone::NotifyBatteryPowerCaps() and RBasicGsmPhone::NotifyNetworkInfoCaps()
have been removed, since these capabilities are static not dynamic.

9) Added MBasicGsmPhoneNetwork::RetrieveDetectedNetworksL() which returns a pointer to 
a CGsmDetectedNetworkResults object which contains information about each detected network.
This information can then be queried client-side, preventing the problem caused by multiple
clients calling EnumerateDetectedNetworks() before GetDetectedNetworkInfo() - the second
function would not be guaranteed to return the correct information. 

The asynchronous version of this function is performed by a separate class,
CBasicGsmRetrieveDetectedNetworks, in a similar manner to the Basic Phone Book async search.
Both synch and asynch variants return a pointer to CGsmDetectedNetworkResults, 
a container class for the information.

10) The same has been done for MAdvGsmPhoneNetwork::RetrievePreferredNetworksL() for the
same reason.

11) CLIP, CLIR and COLP have been moved to the advanced phone level under the 
mixin LineIdentity

12) MAdvGsmLineStatus::TGsmStatus has an extra enum EStatusConnecting, in addition to 
Dialling and Answering.

13) MAdvGsmLineBarring::ChangeBarringMode() now has an asynchronous variant.

14) Minor modifications to Call Forwarding API. Removed BatchCallForwardingInfo as it does
not map onto GSM network commands well.

15) Send SS Strings added on Advanced Phone API.

16) The structure TCurrentNetworkInfo, returned by 
MBasicGsmPhoneNetwork::GetCurrentNetworkInfo(), now contains the class TNetworkInfo as well
 as the location area code and cell ID integers.

17) The "SIM LAST DIALLING" phonebook type has been removed from the Basic API.

	BC with 031 (except GSMADV.dll)

1)  Added a PtrHolder class for the Advanced API, so none of the mixins have any member
	data and the TPtr's are accessed via CAdvPtrHolder.
2)  In ETelBgsm.h, increased size of the TBuf's in the MBasicGsmPhoneId::TId structure
	from 20 to 50.
3)  Hayes.TSY now checks the UID of the fax server.
4)  Added a new type of reqMode for the server-TSY requests; KReqModeRePostImmediately.
    Previously KReqModeMultipleCompletionEnabled had the dual meaning that the server 
    would only allow one request of that particular IPC down to the TSY at any one time,
    buffering the rest and completing all together, and that once completed the server
    would immediately pass it down again to the TSY. 

    Now KReqModeMultipleCompletionEnabled has only the first meaning while KReqModeRePostImmediately
    has the second meaning. 
    Typically the TSY would assign the following values to groups of IPCs:
				
	Those which the 	**Bit mask empty**
	TSY completes 		
	synchronously

	Those which the		KReqModeFlowControlObeyed 
	TSY completes
	asynchronously
	and require
	communication with
	the modem

	Those which are
	notifications,		(KReqModeRePostImmediately | KReqModeMultipleCompletionEnabled)
	or which remain
	outstanding until
	an event occurs
	and then some 
	information is
	fetched.

	Same as above, but	KReqModeRePostImmediately
	for some reason
	the TSY needs to have
	the request from each
	client.

	Those which fetch	KReqModeMultipleCompletionEnabled
	information
	asynchronously.

	 
5)	Registration bugs fixed in the server. 
	Now can only register an IPC which the TSY declares to have the 
	KReqModeRePostImmediately characteristic. Otherwise returns KErrNotSupported.


6)	Bug fix in server allocation of buffer space for the client's data. 
	Data with length 8- and 16-bit can now be stored on the ARM without panicing due to
	word alignment problems.

!!REAL ALPHA RELEASE!!

Unfortunately breaks BC with 030 for Etel.dll, GsmBas.dll and GsmAdv.dll. 
(1) Does not export the internal CPtrHolder - the CBasicPtrHolder class is no longer derived from it.
(2) RTelSubSessionBase functions - Get,Set,CancelReq,GetAndMerge,Register,Deregister - 
	have been changed from public to protected.
(3) This has forced changes in the implementation of RGsmPhoneBook and its derived class
   RAdvGsmPhoneBook, where the active objects CGsmPhoneBookSearch, CAdvGsmPhoneBookRead
and CAdvGsmPhoneBookSearch need to access these functions - they are provided with extra
protected functions in RGsmPhoneBook to access them, and elevated to friend status.
(4) This has resulted in a need for a RAdvGsmPhoneBook copy constructor.
(5) Custom1 code updated.
(6) Tetel code will need to be updated since not all the Rxx objects are closed occasionally 
	causing a heap check panic at the end.
(7) Advanced API has been brought into line with Basic API, in that the mixins have become
    abstract with only pure virtual functions in.

!!ALPHA RELEASE!! 

Breaks BC with 029, even for ETel.dll as the size of the Rxxx classes have necessarily
altered (see below).

(1) Functional freeze. In order to maintain BC from here on in, the Rxxx classes must always
remain the same size. If a new function has to be added to one of these classes it could
mean the addition of a TPtr member variable thus breaking BC. 

To fix this problem, each Rxxx class in core (ETel.h) and basic GSM (ETelBgsm.h) have
a pointer to a CPtrHolder object which contains an array of TPtr's - thus adding a extra
TPtr to this will not increase the size of the Rxxx classes, just the internal CPtrHolder
class.

(2) Extra slots for possible future additional functions in the Basic GSM Mixin classes have
been introduced in order not to break BC. The v'table is therefore not altered.

(3) Client-side Bug fixed in RBasicGsmPhoneBook's asynchronous search, due to the 
copy constructor of the RBasicGsmPhoneBook not functioning properly.

(4) Client-side Bug fixed in RBasicGsmPhoneBook::ReadFirst().

(5) Logging in Release variants for (a) Etel server and (b) Hayes.TSY is now v.limited, and 
is started fresh each time (a) the etel server is started / (b) the phone is opened.
Logging in Debug variants remains the same. 
This should allow the debug variant of the Hayes.TSY to be placed in RAM if necessary, 
and it will be used in place of the Hayes.TSY in ROM. 
To replace the release ETel.dll with the debug variant, a new ROM will have to be built
containing the debug ETel.dll since it is statically linked.

(6) Client-side Bug fixed in asynchronous version of MBasicGsmPhoneNetwork::SetNetwork()

(7) RSmsMessaging::SelectCBSMessages() passes in a TUint16 and a TUint8. On the ARM this
    causes a triple beep reset in the TSY due to the HBufC allocation in the server not
    accounting for word boundaries. Quick fix now on the client side but will have to
    investigate.

(8) Testing:

This release is BC for "core" clients, ie those which do not use the GSM extensions,
but non-BC for GSM clients. 

(1) GSM.DLL has been split into GSMBAS.DLL containing basic GSM functionality and 
GSMADV.DLL containing advanced GSM functionality. Only the former is for ER5, the latter
is not part of the code freeze on 6th Nov 98.
(2) The index of a CBS message has been made a member of the TCbs structure so 
RSmsMessaging::ReadCbsMessage() no longer takes aIndex as a separate parameter.
(3) Added RSmsMessaging::SelectCbsMessages(const TUint16 aId,const TCbs::TDcs aDcs)
which enables a client to choose certain CBS messages and not be told about the rest.
(4) CGsmPhoneBookSearchResults renamed CGsmPhoneBookResults (as it's used for Read results
as well).
(5) RAdvGsmPhoneBook has been added to the advanced GSM API, containing advanced phone book
functionality - 
	(i) Retrieve first empty index in phone book.
	(ii) Determine whether a particular phonebook entry is being used.
	(iii) Multiple Read.
	(iv) Ability to perform basic functionality across all phonebooks, by providing a 
	     name, "AllPhoneBooks", to open a phone book object with.
	(v) Search by number.
	(vi) Search any text (not just comparing with the first letters of an entry).
	(vii) Write and Delete with extra parameter PIN2.
(6) BscGsmCS.h and AdvGsmCS.h now both include "ETelBgsm.h" and "ETelAgsm.h" respectively,
which are the GSM API files.
(7) Ability added to core for certain IPC's, when registered, each client's request will
be passed down to the TSY rather than just one. This solves the problem posed by reading
CBS messages where some clients may want to filter out some CBS messages using the 
SelectCBS function. Then the TSY knows which request is from which client and can complete
the appropriate one.

Passed all WINS tests. Passed limited MARM tests due to RACK-D resource limitations - 
that is NARROW DEB, TETEL, MAKEINI and EFAXTEST.

1) C'tr for RBasicGsmPhone is now exported.
2) Dynamic call caps in core API and Hayes.TSY.
3) Documentation on API's brought up to date.
4) RCall::TCallNotifyInfo now contains call's name.
5) Extra functionality for Call Groups (Basic GSM API).
6) Some functions were not exported in their declarations -fixed TDateTime, 
	MAdvGsmLineForwarding::SetCallForwardingStatusOnNoReply() and its Cancel
7) RCall::Dial(), RCall::Answer and RCall::Connect() now have alternative declarations
   which do not take a TCallParams struct as a parameter.
8) The iStore member of RSmsMessaging::TMsgLocation struct has been changed from a TBuf8
   (which returned narrow names such as "ME","SM") to a TName which will return the more
   user-friendly names defined in the header, which are also the names used to open 
   RSmsStorage objects.

Not binary compatible with 022. 
1) MBasicGsm*** and MAdvGsm*** (*** = Call/Line/Phone) have been replaced by RBasicGsm***
   which inherits from R***, and RAdvGsm** which inherits from RBasicGsm***. The different
   areas of GSM functionality have been hived off into smaller mixin classes which both 
   RBasicGsm*** and RAdvGsm*** inherit from.
2) Dynamic call/line/phone capabilities changing added to core and GSM APIs.
3) Old method Answer() only succeeded on a call with Ringing status, and attempted to answer 
   immediately.
   New method AnswerIncomingCall() may be called on an idle call and remains outstanding 
   on the call until (a) it is cancelled or (b) a call comes in, upon which it is answered 
   with that call. Only one server side call object in the Hayes TSY may have this
   outstanding at any one time, and only one client may have it outstanding at any one time.
4) R***::NotifyInfo() and its associated cancel function is now no longer only at the core 
   level; there are RAdvGsm***::NotifyInfoAdvGsm() functions in Advanced API and 
   RBasicGsm***::NotifyInfoBasicGsm() in the Basic API.
5) RPhoneBook functionality changed slightly. Extra functions:

	ReadFirst(TEntry& aEntry) const;
	ReadPrevious(TEntry& aEntry) const;
	ReadNext(TEntry& aEntry) const;

	RPhoneBook::TEntry now contains the index of the entry.
	
	Search is now performed by calling CGsmPhoneBookSearchResults* SearchLC(const TSearchString& aSearch)

	which returns a class containing the results. The functions

	TInt GetNextEntry(RGsmPhoneBook::TEntry& aEntry);
	TInt GetPreviousEntry(RGsmPhoneBook::TEntry& aEntry);
	TInt GetEntry(TInt aIndex,RGsmPhoneBook::TEntry& aEntry);
	TInt AddEntry(const RGsmPhoneBook::TEntry& aEntry);

	can now be called on that CGsmPhoneBookSearchResults class to retrieve those results.

6) RSmsMessaging class has extra function:

GetDefaultSCAddress(TGsmTelNumber& aSCAddress) 

to return the default Service Centre address on the SIM.

Second Phase Fax Server integration.
Modifed to work with DialStor102 records.

Unicode build removed because faxstore does not have a Unicode build.  Therefore, compilation validated under
Arm and Wins Rel and Deb only.

Testing:	TETEL	 Wins Rel\Deb; Arm Rel
		TGSM	 Wins Rel\Deb; Arm Rel
		T_HyRes1 Wins Rel\Deb
		EFaxTest Wins Rel\Deb; Arm Rel		Multipage faxes Rx & Tx on Wins Builds are reliable.
							Arm Rel build Rx & Tx work unreliably.  Work continues.
							Fax Cancelling is also buggy.  Again work continues.

		EFaxTest Wins Deb			Wins Rel and Arm work continues
							Single page faxes have been successfully Tx & Rx


Fax Details:

We have successfully sent and received faxes using a selection of fax modems (class 1 class 2 class 2)
at speeds of up to 14400 bps.

Current omissions/defects/bugs:

1. We have only tested WINS debug narrow builds and have only managed to run the code successfully under
   the MSVC debugger (i.e. it won't axecute successfully).
2. Fax transmissions always terminate with a stub header on an extra page and an error -25 (KErrEof).
3. Some pages can be shown not to transmit in total (they get truncated) but this has only appeared with
   complex dithering on tests.
3. Fax receptions answer only after the third ring instead the second.
4. The progress structure doesn't seem to be propogating back to the UI.  This is probably the cause of (2) above.

This version is known as 'Static Etel' because it only supports very
limited funtionalities. These limitations are described as follows :
	0) !!! ONLY Win32 DEBUG VERSION SUPPORTED !!! 
	1) Only one server and one session supported
	2) Supported for RTelServer and RPhone only ( not RLine and
       RCall).
	3) All functions within RTelServer are supported
	4) Only the following functions are supported for RPhone:
	IMPORT_C void SignalStrength (TRequestStatus &aStatus,TUint& aSignalStrength) const;
	IMPORT_C void SendMessage (TRequestStatus &aStatus,TMessagePDU  & aMessage ) const;
	IMPORT_C void ReadMessage (TRequestStatus &aStatus,TMessagePDU  & aMessage ) const;
	IMPORT_C void SignalStrengthCancel();
	IMPORT_C void SendMessagePDUCancel();
	IMPORT_C void ReadMessagePDUCancel();
	IMPORT_C TInt Open(RTelServer &aSession,const TDesC &aName,TPhoneAccess aMode);
	IMPORT_C TInt EnumerateLines(TUint &aCount) ;
    5) Etel has been tested with M1 Module (file M1.TSY) - test code
       T_ETEL.CPP

Instruction to get release from R: drive
----------------------------------------
        At fresh drive type
        pgetbld etel group 001
        mnt blddeb
        mnt btstdeb
        mnt rtst - M1 must be connected ( with appropreate SIM card) 
        to PC Com 1 before runing this test

Version 0.1 (002)
=================

        1) No new services other than release 001
        2) Now supported Arm variants
        3) Additional mudule DTSY.TSY is now part of the release.
This module is known as Dummy Tsy which is use mainly to test etel.dll
without any hardware. Clients of Etel can use this to test their code
prior to hardware availability by create dummy scenarios.
        4) Test code for testing with Dummy Tsy is called TETELDLL
 
Version 0.1 (003)
