What we have found (through inspection with a scope) is that from left to right (when looking at the RC in the normal orientation), the pins are +5, Tx, Rx, and Ground.

I don't know if this is considered "confirmed" or not, and we are one of the teams having trouble with that port, but we are currently able to use the TTL port as a TX-only port using that pin configuration... (RX is where we're having trouble)
