Subject: MXO-KP28.ASM new Kaypro overlay for MEX

MXO-KP28.ASM is a new MEX Overlay for Kaypro Computers with either
internal or external modems.  A full-featured SET command processor is
implemented to select between modems as well as set specific
characteristics of each one.  The file is now available from SIMTEL20:

       Filename                Type     Bytes   CRC

MICRO:<CPM.MEX>
       MXO-KP28.ASM.1          ASCII    37584  D19EH

The following table outlines the SET command options:

               activates modem)

Recent revisions:

8/26/84  2.8  Added equate to support Anchor Signalman Mark XII modem.
                This overlay now supports DSC, dial abort (^C),
                and accurate SET DELAY processing for Anchor modems.
                Also incorporated the PARITY, STOPBITS and LENGTH
                commands from the Norm Saunders overlay (MXO-KP3X) in
                an attempt to unify the Kaypro MEX overlay identity crisis.
                The new SET commands are NOT implemented for the 4'84
                internal modem.  The SET ? command and the SET without
                arguments correctly distinguishes between the internal
                and external modem support.          Terry Carroll

8/03/84  2.7    Added call to DISCON: (disconnect routine) in the
                Smartmodem dialing routine at SMDMOFF:.  It appeared that
                when either the delay timer timed out or a CTRL -C
                abort coincided with a connect, the modem did 
                connect, even though the overlay responded with
                NO ANSWER. Added these calls to make sure there
                is no unannounced connect.     John C. Smith
