Back when I investigated, it appeared to be TTL signal levels instead
of RS232 signal levels. Mind you, this was a type-3 keyboard, not a
type-4. But throw on a level shifter to get RS232 signal levels and
yes, it would be boring old 1200 baud.

It's in the Sun docs; if you have trouble finding it, drop me a line
and I can supply it (assuming I can find that piece of paper :).
