Tutorial on programming devices?

[Enno Middelberg]

Hi,

I want to write some code to read data from my GPS receiver. The
signals will arrive via a serial link which I want to process and
store.

I do not have a clue on how to read/write from/to devices using
Python. So far, I have only written scripts to process data stored in
files. Does anybody know a good starting point for reading or a
tutorial?


Many thanks,

Enno
