--------
It's the same printer port as VSC. It expects a baud rate of 600, 7 data bits,
1 stop bit, and no parity.

@ -17,6 +17,7 @@ Hardware notes (6085):
This is on the SC12B board, with enough modifications to support more leds and
magnetic chess board sensors. See sc12.cpp for a more technical description.
Like SC12, the printer expects a baud rate of 600, and 7 data bits.
The first RAM chip is low-power, and battery-backed with a capacitor. This is
also mentioned in the manual. Maybe it does not apply to older PCBs.
