as i didn't get any replies to my query about setting-up my netcom modem, i did some reasearch in the web. i am very relieved that i finally got it going after many trials and errors. one of the more interesting experiements was changing its mtu as advised by http://www.howtonetworking.com/VPN/mtu4.htm
i finally settled for 1462 and, i can see that the data rate jumped from 1900 to 5600 kpbs! i am not tech-savvy enough to understand its signifiance but i could feel that the internet is faster!
am i justified to feel happy? btw, do i have to update my local machine's registry as mentioned in that site?
