Hi,

I am trying to connect to Internet using Wavecome modem with Airtel GPRS connection. I am able to successfully connect and browse the Internet using wvdial. But if I use pppd, I am getting the error message as "LCP Terminated by peer".

The exact error I am getting is pasted below.

[root@pscu1320 ppp]# pppd call gprs-wavecom
GPRS modem init: press <ctrl>-C to disconnect
Wakeup Modem

I am attaching "chatscript" and "options" files which I am providing to pppd.

The directories in which I have saved the attached files are:
gprs-wavecom - /etc/ppp/peers
gprs-options - /etc/ppp/
gprs-wavecom-connect-chat - /etc/ppp/chatscripts

Thanks in advance.
