The printer port is either a 4800 baud port intented to drive the printer, or a
9600 baud at the standard console UART address. Which it is depends on the
connected cable; BCC05 is for printer, BCC08 is for console. Or you can wire
your own. The difference is that one (the BCC08, I think) has a jumper which
tells the hardware to be a console.
