- Re: MDM7 overlay for Kaypro allows 4800 baud
-
- I have modified M7KP-2.ASM in several ways that serve my needs.
- Others may have similar needs, and may find the revised file
- (M7KP-X48.ASM) useful.
-
- The primary purpose of the mod is to facilitate the direct 4800
- baud (i.e., RS-232 to RS-232, without phone lines) transfer of
- files to and from KAYPROs. I find that very useful -- I do some
- work on the Kaypro, or my subcontractors do, and then I can
- upload to my S-100 and continue to process the data into a single
- report.
-
- This can easily be done with three wires. I explain in the file
- how to do it, including a diagram for a simple cross-over switch
- to match the other computer's RS-232 configuration (I installed
- such a switch into the RS-232 connector itself).
-
- But most importantly, the file is set up so that by saying YES or
- NO to two equates, one can also assemble it for normal modem
- operation, and one can set it up to run off the KP-n-84's serial
- PRINTER port. That is useful if you do not want to unplug your
- regular modem whenever you want to transfer a file direct at 4800
- baud.
