Hacks for Intel 9600EX with Xenix/386 2.3

[Randy Bush]

The following hacks run the Intel 9600EX 'Fast Eddie' modem on Xenix/386 2.3.x.

Note that this runs the modem with the computer-modem baud rate locked at 9600
while the modem-modem rate floats, so that callers do not have to whack that
disgusting break key to cycle the getty's baud rate.

Should you wish to lock the modem at a higher baud rate, and I recommend doing
so *after* getting it working at 9600, then hack all the B9600 stuff to EXTA,
and all the 9600's to 19200.

Good luck, and happy modeming!
