FW: Comunicating through COM ports

[Kevin Cazabon]

If you want simple access to Serial ports, try the "uspp" module
written by Isaac Barona: 
http://balder.prohosting.com/ibarona/en/python/uspp/uspp_es.html

I've been playing with it, and it's VERY simple to use... the posted
version needs one small modification for W2k/Python 2.1.1, but the
author is currently fixing that.

FYI, the mod is:  comment out / remove the reference to
"win32con.FILE_FLAG_OVERLAPPED" in the SerialPort_win.py module.
