It's a generic 'debug' header with GND, PWRx2 (IIRC) and GPIO pins 
connected directly to the FPGA. It's meant for custom expansion and 
generally requires changes to the FPGA, although I seem to recall Gary 
programmed some 'default' behaviour at one point?!?

Don't go plugging in serial cables...
