MXO-ON2 is a full-featured combination hardware and modem overlay for
ON! computers. It is based on the MXO-KPS4 overlay for the Kaypro and
on Joe Wright's T3M-ON1 Term III overlay for the ON!. It features full
support for all major features of the Z80 DART including send-break and
setting word length, stop-bits and parity. Both true Hayes-compatibles
and the semi-compatible Anchor modems are supported. MXO-ON2 was
created out of my personal preference for MEX114 over the IMP program
supplied with the ON!. IMP is a fine program within its design limits,
but is severely lacking in flexibility for a dedicated MEXer like me.
In general, MEX will operate in the same manner as with the ancestor
Kaypro overlay, with the notable exception of radically re-written SET
ANSWER and SET ORIG commands. SET ANSWER now suspends MEX until a
validated modem call is received or until a control-C local abort. This
will enable the astute MEX user to set up looping READ files for limited
unattended access to the ON!, although it is no substitute for the true
remote console capability of BYE or MEX Plus. READ files that use this
style of SET ANSWER can be found in the MEXWELCM.LBR file I released a
couple of years ago for the old MXO-KP41 Kaypro overlay, which
inadvertantly implemented the capability, but only for the internal
Kaypro/TI modem. It would be a relatively simple matter to implement
the enhanced SET ANSWER and SET ORIG commands for other combination
hardware/modem overlays for MEX - the MXO-SBSx series for the SB180 are
also of the MXO-KPS4 lineage and are very good candidates for this hack.
