Subject: MXM-2403 new small 2400 overlay for MEX

In SIMTEL20 directory PD:<CPM.MEX> you'll find MXM2403.AQM,
MXM-2403.DQC, MXO-KP43.AQM, and MXO-TV13.AQM (and temporarily
MXM-2403.LBR which contains all four).

MXM-2403.ASM is version 1.3 of the MEX overlay for external Hayes
Smartmodem 2400's and US Robotics Courier 2400's. NOTE that you will
ALSO need a serial port overlay to use with this one..  Your serial
port overlay should NOT have any dial routine or special code to
support Smartmodems or it will conflict with this overlay. The
MXO-KP43.ASM and MXO-TV13.ASM overlays included in this .LBR file are
examples of "basic" overlays.. (KP43 is for most Kaypro computers and
TV13 for the Televideo TS-802.)

The patch process, if followed as shown in the DOC file, should work
provided you find the proper overlay for your system and assemble them
with ASM or MAC or RMAC or M80.. (Some overlays may not assemble
properly under ASM, read the comments in the overlay...)

Be sure to get the MEX114 version which supports 1k packet mode,
especially important at 2400 baud..
