seems that others too want to use the serial port from python...
here's my module (python license). The current version is 1.12.

from the readme/homepage:

This module capsulates the access for the serial port. It provides
backends for stadard Python running on Windows, Linux, BSD (possibly
any POSIX compilant system) and Jython. The module named "serial"
automaticaly selects the appropriate backed.

- same class based interface on all supported platforms
- port numbering starts at zero, no need to know the port name in the  
  user program
- port string can be specified if access through numbering is
- support for diffrent bytesizes, stopbits, parity and flow control
  with RTS/CTS and/or xon/xoff
- working with or without receive timeout
- file like API with "read" and "write"
- The files in this package are 100% pure Python.
  They depend on non standard but common packages on Windows
  (win32all) and Jython (JavaComm). POSIX (Linux, BSD) uses only
  modules from the standard python distribution)
- The port is set up for binary transmission. No NULL byte stripping,  
  CR-LF translation etc. (which are many times enabled for POSIX.)
  This makes this module universally useful.
