In addition, it requires something called  "Java Communications" (JavaComm) extension for Java/Jython, doesn't provide a link to it, and when I google it - google returns the page I came from!

The interface stuff, hmm I'm not quite sure what you are on about you 
access ports through the win32 API which is the 'driver' - you could 
probably bypass this and start playing around with assembly code but 
there's no point!!
