While installing MDM724 (from 712) I noticed a fairly serious omission in the documentation. There were no equates for the entry points into the main program from the overlay. I don't know if this was an oversight or if there was some earlier version which explained them. I would like to make a suggestion to those responsible for updating this great modem series. WHY DON'T YOU PUT A JUMP TABLE IN THE MAIN PROGRAM FOR ALL YOUR ENTRY POINTS? AND LEAVE IT THERE. IT WORKS GREAT FOR YOUR BIOS, DOES IT NOT? That way we poor souls out here won't have to search through dumps to find the new addresses everytime there is an upgrade. Jesse (happy modeming) Eaton.HFED@HI-MULTICS

I was aware of the jump table located within the overlay itself and up
until tonight (this morning) I was under the impression that all those
little "DS 3" pseudo ops had to be replaced by "JMP's" into the main
program.
When they call them overlays they mean it. Those DS's leave nice neat
little undisturbed jump instructions from the orignial .COM file,
"because" as "everyone" know's a DS does not alter memory.
Therefore my overlay, your overlay and everyone else's overlay will
"plug in and play" on any version of MDM7 after it has initially been
customized and optioned. It's a one shot operation.

P.S. Thanks for the USR overlay Bob, I'll blend it with mine and
shoot you a copy somehow.
