Plain RS-232 should be fairly simple under Mac OS X once you get such 
an adapter. They include a driver that creates a device under /dev, 
which can be used as a regular serial port after you open it from your 
application (so if you search for generic unix serial port controlling 
code, it should Just Work).

USB will be a lot harder, I think, though I have no experience with 
that. Your code for Windows will also be quite different (whichever 
route you take), I assume.
