Called when a bad frame is received. No action is currently taken.

RecvFrame() is called instead when a good frame is received

Abort the protocol.

Perform validation checking on the option list of a ConfigAck or ConfigReject.

Close the state machine and protocol. Called by the derived class on closing.

Perform validation checking on the option list of a ConfigRequest.

Construct the state machine object

Generate a new nonzero packet identifier.

Begin the state machine and protocol. Called by the derived class during initialization.

Handle a received packet with an unknown code.

Perform validation checking on the option list of a ConfigAck or ConfigReject.

Send a Code Reject or Protocol Reject packet.

Initialize the restart count and wait time with values appropriate for the config phase.

Initialize the restart count and wait time for with values appropriate for the termination phase.

Delete any existing request list, then create a new one. Initialise counters for sending config requests.

Called when the lower level protocol is killed.

Signals the Down event. Called when the lower layer protocol has gone down. This means that our layer can no longer receive or transmit anything.

In case of LCP, this means that the physical link is closed (e.g. Peer dropped DTR) If we are LCP, this may mean that PPP is finished, because the link is no longer available.

Called when the lower layer protocol has come up.

Allocate a new packet buffer and info header. The caller must fill in the the packet and call its Pack() method before sending.

RPppOptionList::CreatePacketL

Handle ConfigRequest, ConfigAck, ConfigNak and ConfigReject

Handle Config Request with no options.

Handle a Code Reject or Protocol Reject. If the reject rejects a code (or protocol) that should be known terminate layer. (Note, As the behaviour of protocol reject is the same as code reject, this function handles protocol reject for LCP)

Handle a Terminate Request packet and cleanly terminate the connection.

Reads the contents of the ppp.ini file.

Receives and processes a PPP frame. Called by CPppLcp .

FrameError() is called instead when a bad frame is received

Reply to a config request with a set of options.

Send the config request in iRequestList

Update the options list and send a new config request after a Nak.

Update the options list and send a new config request after a Reject.

Initialise request list and send a request if successful.

Send the first Terminate Request packet to begin connection teardown.

Send a Terminate Ack packet.

Send a Terminate Request packet.

Set the next state in the FSM. Cancels the timer when appropriate.

Tear down the protocol, regardless of the state of the FSM.

Called by MTimer on timer expiry.

Clear the restart count.

If MPppFsm is to be terminated.

Why PPP is shutting down

Maximum TerminateRequest transmissions.

The physical layer may block on its own retries when trying to send an initial config packet which then blocks the LCP from shutting down until attempts to send a disconnect packet have timed out. To allow for a quick shutdown in such cases where there is no evidence that the link layer is working the EPppFsmStarting state also sets this flag. This is driven by INC85191.
