I would like to use the serial port with an external clock for some hardware
I am making.  (An audio digitizer running at ~400 kbaud.  The final cost
should be under $20.  I will post the plans to the net if anyone is
interested after I have finished it.)

The serial driver section in my copy of Inside Macintosh (Phone book version)
does not tell me how to use the external clock, nor does it tell me how
to change the clocking frequency from whatever it usually is (16 times
the baud rate, I think) to equal the baud rate.

I remember that when the Mac came out the "virtual slot" concept gave a
maximum data rate of ~1 Mbaud with external clocking, ~400 kbaud with
internal clocking, but IM does not tell us how.
