I am sure this is a repeat thread but I strongly believe that this bears repeating. After the Chesapeake regional, I found many teams that did not know about their competition port. Last year I built the circuit to disable our robot and test autonomous with the real auto loop. The simple schematic can be found here:

I put ours in a radio shack project box to make it look nice and not fall apart.
This is a great practice circuit for new electrical people to learn soldering and how to deal with those serial ports.
