Hello! I'm working on a TPDD hardware emulator using low-cost off-the-shelf-components. I can't find much online about the specifics of the serial connection between the M100 and the TPDD. The TPDD protocol page on the wiki mentions 19200/9600 baud, but nothing about flow control or how it negotiates the speed.
Based on trial-and-error, I did figure out that hardware flow control is needed before TS-DOS will try sending any data. This gives me something to work off of, but more details would be great. Thanks, Jimmy
