Even more valuable is http://www.python.org !

The OP didn't specify which platform he was using.  If it's Windows,
the above won't work of course, as you pointed out... in either case,
using http://pyserial.sourceforge.net/ is his best bet.  That 
module will allow greater control over various aspects than the raw
/dev/ttySxx approach and this sort of thing is often, though not
always, essential for talking to devices such as a GPS.

To the OP: check the link above and the archives for similar questions 
and examples.  If you still need help after that, feel free to post
here again!
