don't think this works, how would python know you didn't want a file 
called "com1" (windows).

On windows for a serial you normally suffix a colon, which would be very 
nice if it worked ( it does in the windows kernel32 ) but i think you 
need a library ( several avilable ) you see i think there might be setup 
differencies between systems as well as addressing.

I've been thinking about a proxy server that maps a socket to a local 
serial port ( terminology betrays the common heritage ) there are 
commercial examples of this around. Ideally you just need the one for 
your system, it sort of acts like a high level driver using socket comms 
as the known bridge.
