[lwip-users] PPP connect to T-Mobile GPRS (Hungary) problem

[Szabó András]

Hi!

I'm trying to connect to gprs using the CVS code PPP, and i've managed to get to the point IPCP starts to do something, but suddenly an LCP terminate arrives, and NO CARRIER. Bah :)

It's a hack of the unix port in the contrib to work on my linux with my irda Siemens S45 phone. I have a GPRS account at T-Mobile, that has no user/password (under windows it works with user/pass leaved blank). I'm in Hungary, Europe.

Read: means the serial input characters from the serial port in hex
Write: ---"--- to the serial port.

I'm not an expert about these fancy protocols, such as LCP, IPCP, PAP and so on, i'm a bit stuck :) Maybe one of you see some sense on these codes and can help me, it would be great!
