You mean 36000bps, right?  I can't believe a disk drive can be
just a little faster than a 2400bps modem!

The IIGS serial ports are not restricted to RS-232.  In fact,
they are another standard RS-4?? something or other.  The comm
chip int he IIGS is very good at doing many different tasks.
If a serial port can be programmed to do nonstandard things, it
has to be the IIGS'.

The IIGS comm chip can handle AppleTalk, which is very timing
sensitive.  AppleTalk is 230,000bps!
