You are absolutely right when it comes to handling the sppp driver in manual
mode. The user creates a Up event using ifconfig and a Open event moves the
fsm from Starting(1) to Req-Sent(6).
In my case, although, I want to use the IFF_AUTO (dial on demand) option and
this is where ifconfig can not help me. In the auto mode, the sppp driver
should initialize the lcp machine when it gets a new message to send. In
line 646 (sppp_output) you can see a call to Open the lcp but because there
was no previous Up event, the fsm moved from the Initial(0) state to the
Starting(1) state and not to the Req-Sent(6) state.
I think that in the auto mode, there should be an automatic call to the Up
event, no?
Thanks
Daniel
