Ah, that could well be.  I haven't tried it - I didn't discover the
baud-rate hackery until I'd stopped using Sun-3s for graphics.  And I
don't use Sun-3s for any other serial input with a data rate higher
than human typing, so....

There are two baud-rate select pins, at least in the model I have
(Mouse Systems "MSC 401162-035/A", "SUN 370-1170-01").  Three of the
rates supported are 1200, 4800, and 9600; I forget the other one, but I
don't think it was 2400 - I recall them not making sense, and 2400
would make sense.  600 maybe?
