The M100 native display has some important non standard control codes. Supposing you could read inbound characters on the serial port, the egress flow could be "almost VT100" for display purposes.
A really useful project would be to modify a terminal program to speak the custom M100 display codes. This would allow a PC to really emulate a proper DVI video. The codes and what they do are well defined....this is what I have implemented in that MVT100 hardware adapter, and what both the VT100 driver and REX# supports. Side comment. Even with all the extended codes that a true VT100 supports, there seems to be no way to make a VT100 properly handle a few of the M100 control codes. ..steve On Thursday, October 6, 2022, Mike Stein <[email protected]> wrote: > Doesn't Steve's program handle the display part?
