The tether port does use RS-232. HOWEVER: don't hook a laptop up to this port as +12v from the robot battery is provided on one of the pins. In theory this shouldn't damage anything since RS-232 has a range of -25v to +25v, but I think it would be extremely unwise to try it.

If you're interested in this kind of thing though you should come check out the Wildstang pit and ask an electrical person to show you the Mini Controller we made. We built a little circuit with a microcontroller on it that speaks directly to the robot controller over the tether port. It has a couple of momentary switches on it to retract the hooks and a push button to perform a robot reset. We use it to unhook from the goal after the end of a match rather than carrying out the whole control system onto the field.
