Do you have specific requirements which forbid the use of SLIP? I can 
confirm that lwIP works well on my 68k target with SLIP. Much simpler and 
uses less code.

I've not yet been able to get lwIP PPP to work on my target. It sends 
packets, and the other endpoint, too, but a connection is not established. 
My knowledge about the PPP protocol is a bit poor, so I failed to find the 
cause of the problem. I hope others on this list had more success, it would 
be interesting to know on which target systems it worked.

BTW I'd like to ask if someone could provide a working example of lwIP PPP 
options/initialization plus the pppd configuration of the other endpoint 
(e.g. Linux).
