I realize this. I tried connecting to different port "numbers", but I have not tried the serial.Serial(COM1). I wasn't sure if that worked, but I know a quick way to find out. > Try using the actual name of the com port (e.g. 'COM3' or > 'COM5') instead of 0. The com port used in Hyper Terminal is COM40.

That might become an issue when I try to read COM40 for the GPS bluetooth transmission. This issue does not relate to why I cannot open smaller com ports, though. -- http://mail.python.org/mailman/listinfo/python-list
