For testing purposes log in as root and open two different shells.
In one shell issue the command
tail -f /var/log/messages
Start the PPP connection in the other shell using the command
ppp-on
In the first shell you will see various messages indicating that the modem is initialized and that the connection is being established. My /var/log/messages looks like this:

Now open your browser and get started.
In case the browser gives the error that the server name is not being resolved, open the file /etc/resolve.conf and add the entry
namesserver 202.41.97.9 nameserver 202.41.97.132 |
These are two valid DNS servers of Ernet India Labs, located in New Delhi. Your Internet Service Provider probably provides its own name service, use the IP addresses of the servers they recommend.
When you are finished surfing the net you may stop the connection using
ppp-off
in the second shell. In the other shell window you will get something like this :
May 29 06:16:15 dhiraj pppd[2341]: Terminating on signal 2. May 29 06:16:15 dhiraj pppd[2341]: Connection terminated. May 29 06:16:15 dhiraj pppd[2341]: Connect time 2.2 minutes.
