If you're getting a normal CONNECT
when using a terminal program, you should be able to get the same results using lwip. I am using lwip,
together with my own implementation of PPP. AT commands I use to get the PDP
context are implemented in yet another part of the software, as they have
nothing to do with PPP.
Are you able to monitor what your program is sending to the
modem? (Split serial cable)
By doing that you should be able to see the differences and
decide what is wrong

Hi,
I've used the following AT
commands to establish a PDP context :
ATZ
AT+CFUN=1
AT+CMEE=2
AT+CPIN="0000"
AT+CREG=1
AT+CGDCONT=1,,"network_name"
ATD*99***1#
And it works perfectly on a
hyperterminal. The same thing through LWIP, PPP and my GPRS module doesn't
work.
Thanks,
Regards,
Laurent
