Subject: Courier/Hayes 2400 MEX overlay

  The long-awaited  Courier 2400 (and Hayes 2400) MEX overlay is now
available, on SIMTEL20:  MICRO:<CPM.MEX> MXM-2400.ASM. 
  This MEX modem overlay is intended for 2400 baud Hayes and Couriers
(but probably useable w/2400 baud modems as well).  Supports "fallback"
of data rate making each call at a maximum (dflt 2400) rate, switches to
a lower rate if the remote modem can't handle the higher.  If the USR2400
switch is set, it supports the Courier's adaptive dialing, automatically
sets the Couriers busy detector, and supports  "RINGING" and "VOICE"
status codes.                          --Ron Fowler
