     You're assuming that the serial ports are RS-232, which is
spec'ed to only 20 KBaud.  However the MAC ports are RS-422, which is
designed to operate at 10 MBaud over distances less than 40 ft.  You
should have no problem sampling at 22K as long as the external
digitizer will drive the line that fast.

Hope this helps
