There is a python library at 
http://personal.telefonica.terra.es/web/babur/uspp/uspp.htm that is GPL 
and I know works because a friend uses it all the time.  It shows how to 
do serial communications on Linux, Windows, and Mac.  All three are a 
little different due to how each OS handles things like setting the baud 
rate, which files actually represent the serial port, and other similar 
things.  That being said, I don't think it would be a huge effort to 
simply port this code from python to either M files (might have to add 
some oct stuff for tcsetattr() calls and such) or simply porting it all 
to oct files.
