Hi All, Thanks for your responses, it was a problem with the ser.cfg file, when i used the one available on onsip.org as suggested, ser started flying :-) ! One more problem i faced was that, when the config file is downloaded from the internet, not in zipped format but one-by -one, there seems to be some html formatting that comes along with it, leave alone the HTML tags, once that is removed, there are some more problems like the > and < symbols in the Expressions of ser.cfg, will also be turned int thier HTML representation, with a &gt; or something, once that was also removed and replaced with the actual symbol, things seemed to work for me. Thank you. Cheers.
