→ port.serial general information about the serial port, serial port cable, etc.
There is an unfilled five-pin header labeled JP1 which is a 3.3V TTL serial port. Experimentation with an oscilloscope indicates that it runs at 115200 8N1, but I'm waiting on the arrival of my serial adapter to verify. I believe this is the correct pinout, but I'm not certain about RxD and NC.
