|
26 * \section intro Introduction |
|
27 * |
|
28 * This CSY has been designed and implemented by TapRoot Systems. |
|
29 * This CSY is part of the TapRoot Systems Communications Platform (CommP) |
|
30 * product family for Symbian OS. Please contact TapRoot Systems for |
|
31 * information on CommP. |
|
32 * <p> |
|
33 * A CSY is a specialized type of DLL that implements API interfaces |
|
34 * required by the C32 Serial Communications Server. "CSY" is the file |
|
35 * name extension used by CSY modules as in "ecuart.csy", which is the |
|
36 * name of Symbian's generic CSY for non-multiplexed serial ports. |
|
37 * TapRoot Systems 27.010 CSY (gsm0701.csy) is compatible with the |
|
38 * 3GPP 27.010 v5.0.0 specification. |
|
39 * <p> |
|
40 * The CSY has been designed and tested with the Intel Lubbock application |
|
41 * processor, TI Condat baseband processor and Symbian OS 8.0a. |
|
42 * The CSY is not guaranteed to work with other AP's, BP's or Symbian OS versions. |
|
43 * The CSY has been integrated with Symbian OS supplied TSY and NIF IP. |
|
44 * The CSY is not guaranteed to work with other TSY's and NIF's. |
|
45 * |
|
46 * \section feat Features |
|
47 * |
|
48 * The CSY supports the 27.010 Basic Option. The 3GPP 27.010 specification |
|
49 * is derived from the GSM 07.10 specification. 3GPP 27.010 defines a mechanism |
|
50 * whereby multiple commands and data streams can be carried over the same |
|
51 * physical link. This specification defines a multiplexing protocol between |
|
52 * a Terminal Equipment (TE) and a Mobile Station (MS) allowing multiple |
|
53 * simultaneous sessions over a single start-stop, framed, serial link. |
|
54 * Each session (channel) can carry different types of data including voice, |
|
55 * fax, data, SMS, CBS, phonebook maintenance, battery status, GPRS, USSD, etc. |
|
56 * <p> |
|
57 * The multiplexer has three operating options, basic, advanced without error |
|
58 * recovery and advanced with error recovery. CSY 27.010 supports the |
|
59 * basic option. The basic option is recommended on highly reliable links. |
|
60 * Advanced options are not supported by the CSY. The characteristics of the |
|
61 * basic option are: |
|
62 * <li> Length indicator used instead of the HDLC transparency mechanism |
|
63 * <li> Different flag octet from that used by HDLC |
|
64 * <li> Cannot be used on links that use XON/XOFF flow control |
|
65 * <li> May have longer recovery procedure from loss of synchronization |
|
66 * <p> |
|
67 * Each channel between the TE and MS is called a Data Link Connection (DLC). |
|
68 * A special DLC called "control channel" is used to exchange management |
|
69 * information (e.g. parameter negotiation), power saving control information, |
|
70 * testing, flow control, close down, etc. between the TE and MS. |
|
71 * <p> |
|
72 * The multiplexer is activated with the 3GPP 27.007 AT+CMUX command. |
|
73 * <p> |
|
74 * |
|
75 * \section install Installation |
|
76 * |
|
77 * Refer to the readme.txt file for installation and build instructions. |
|
78 * <br> |
|
79 * Please contact TapRoot Systems for information on product updates and |
|
80 * additional support. |
