Dear Reddy,
I tried again, now I have changed the baud rate in wvdial.conf. Now after doing wvdial Reliance, I get the following message
Quote
--> WvDial: Internet dialer version 1.56
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.

Requesting your help,
