[lwip-users] LWIP-PPP on ecos and GPRS

[Sebastian Block]

Hi,

I have a problem connected throught GRPS to my ISP using PPP
I can auth at the ISP but than
the problem begins with turn to the IPCP, where you should normally get an IP
and so on.

I've added the output from LWIP-Stack in hope you can read out more of it.
I marked a line with <---- this line, in cause of that there should be memory
allocation problems, but I can use the same Kernel (only switching the
SerialLine which use to connect) to connect to my linux-machine with ppp and
with local serial line (no GPRS) it works fine.

I hope you can help me

 Sebastian
