It depends on your platform, as the std python distribution doesn't
have platform specific serial io modules and accessing serial ports is
not defined by C.

If you happen to be using a unixish system, just opening
the serial port and using the termios module or stty(1)
should work.

You are doing it wrong then :) If you tell us how it fails to
work, people may be able to help.

so the newsgroup/mailing list doesn't get fooded with
