[lwip-users] PPP and lwIP

[Selwyn Jackson]

I am trying to get PPP and lwIP to work.  I seem to be missing something in
my setup, as the PPP and TCP/IP layers do not seem to work together.  I am
starting ppp and tcp after the modem has connected.

I think I have a PPP connection (is this so?) - I get the following
messages:

L5 lcp_reqci: rcvd MRU 2000 ASYNCMAP=A0000 PCOMPRESSION ACCOMPRESSION
L5 lcp_reqci:  MAGICNUMBER (D7D0990D) PAP (C023)
L5 lcp_reqci: returning CONFACK.

After this the upper layers do not seem to connect:

Error -3 set in call back

Any help would be appreciated
