Hi all,
  I've traced the messages I send to the server, I have an Hexa display of 
these messages but where can I find the valid Hexa frame for a Confack message 
(for exemple) ? I've tried the PPP RFC 1661 but there's not the level of detail 
I am looking for. I would really like to see the entire frame in hexa, to 
compare with mine and see if I missed an option or something.

thanks,

Laurent Vanstaen

The problem is that I try to connect to a GPRS APN (Orange) using PPP, so I 
cannot configure the server side. It seems that this APN wants to use Protocol 
Field Compression and Address/Control Field Compression. Does LWIP PPP support 
these options ? I think so but I'm not sure.

I saw that happen when directly connecting to a PPP server on my linux box 
(via a serial lead). It's appears to be caused by bad handling of unsupported 
compression options during the PPP setup phase (the solution I used was to 
disable those compression schemes at the server end).
