www.pyhton.org is a very valuable source on these things.

And besides that, isn't reading/writing from some port (almost) the same as
read/write to a file? Just use /dev/ttySxx (with xx your port number) as
filename. Supposed to work like that (never tried myself). Just a thought.

Oh if you are not in Linux/Unix/etc it will probably be different. In DOS I
had to send commands directly to a port (that was a project using Turbo
Pascal, felt to me as a pretty 'hacky' way of reading and writing your data,
using interrupts and all).

Good luck anyway!
