Have you looked at USPP ?

There was an announce post (found back with google groups):

USPP (Universal Serial Port Python) Library v0.1            
            ------------------------------------------------            

Multi-platform Python module to access serial ports

USPP Library is a multi-platform Python module to access serial ports.
At the moment, it only works in Windows and Linux (the platforms I have
access to) but as it is written entirely in Python I hope you can extend
it to support any other platforms.

The module has the following features:

- hight level access to serial port under several platforms. -
autodetects the platform in which it is working and exports the correct
classes for that platform. - object oriented approach. - file object
semantic operations over the ports. - allows using the serial port with
different speeds and characteristics. - RS-232 and RS-485 modes (now
only RS-232). In RS-485 mode the communication is half-duplex and uses
the RTS line to control the direction of the transference. - blocking,
non-blocking or configurable timeout reads.

Maybe it can help (at least you may look into the code).

A+
