IFI has the pinout for the competition port available
Here (PDF), if you'd like to construct a dongle. We used a dongle on 195, but I've heard it's just as easy (in a pinch anyway) to stick a wire between the pins to access disable or autonomous mode.
razer: Are you familiar with how programming for the FRC works? it's loop-based, not like any entry-level desktop programming (Visual Basic, .Net, PHP) you might have done. The loop is called every 23.6ms (is about, it's been a while). so your code is executed every loop, and when autonomous mode is over, the loop is no longer called.
