PCMCIA modem PPP issue

Hi,

I am posting a PPP question here for lack of a better forum to post in.
I am working with a Cingular Aircard 860 PCMCIA modem, and am having
trouble with the PPP connection. From the log, it looks like the CHAP
authentication is happening but later somewhere in the LCP/IPCP
negotiation process there is a problem. I'm attaching the PPP options I
am using and the log.


options
----------
-detach
/dev/ac850_5
57600
debug
asyncmap 0
nodefaultroute
usepeerdns
noauth
user ****
password ****
show-password
crtscts
lock
connect '/usr/sbin/chat -v -t3 -f /etc/ppp/peers/ac850chat'

ppp log:

Connection terminated.

In particular, I am concerned about the "Protocol-Reject for
'Compression Control Protocol' (0x80fd) received" line.

Can anyone tell me what is happening here?

Thanks in advance.

What about news:comp.network.ppp ?

A rather recent thread in comp.network.ppp discusses about a similar
problem with PPP over GPRS. Subject : "Peer terminates PPP connection
after establishing (successful?) a connection"

[Supersedes to fix erroneous newsgroup name]

What about news:comp.protocols.ppp ?

Thanks for the suggestion. I will try that group also.
