Sounds like you're trying to get the MIDI baud rate.  Just thought I'd mention
that I recall the best approximation to the MIDI rate on the Mac's SCC is a
bit off, because of the clock/counter/divider setup in the hardware.  Thus
the profusion of MIDI adapters for the Macintosh, which provide an accurate
clock as an external clock to the SCC.
