My reason for asking is that I want a diagnostic system that will work when the FRC isn't hooked up directly via parallel port, and can't afford (the Team can't) to shell out $100+ on a wireless radio set for the RS232 port.

The short answer is no. The four Joystick ports on the OI are inputs to the OI only (with the exception of a small amount of +5 volts coming out of the OI to read the joystick potentiometers).
The Dashboard port is exactly what you are looking for, however.

The ideals that are held by myself and by many of the longtime FRC mentors and volunteers whom I consider friends and colleagues are bigger than FIRST, and we will find (or make) another vehicle for them if we are forced to. - Jared Russell [more]
