Testing Cell Modem Option GT MAX on Cingular

[Phil Meyer]

Our provider is switching cell cards on me (again) and this time its not 
a standard PCMCIA to USB serial interface.

This card requires a special driver, and I found nozomi.

The driver allows communication to the card ok.  The problem I am having 
is a proper response from Cingular.

After CHAP succeeds, pppd sends a request for a local IP and DNS 
servers.  Cingular sends back ONLY the DNS servers, and NOT my IP. :(

I have tried a variety of settings in the ifcfg file to no effect.  Here 
is what is there now:

 -> cat ifcfg-cingular
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=no
USERCTL=yes
PEERDNS=yes

And here is a debug log:
