Perhaps a combination of DOSbox or virtual software running Desklink can help you to communicate and transfer files to and from a m100. Another program can be used to capture to/from serial data and reveal protocols for different use case conditions. It may be possible to do things the other way around: the virtual m100 program can log serial port data I believe. Perhaps a TPDD could be connected to the host computer via a serial or usb to serial adapter? Any more experienced people with thoughts on this? ________________________________ From: M100 <[email protected]> on behalf of c646581 <[email protected]> Sent: Tuesday, July 17, 2018 10:50:58 PM To: [email protected] Subject: [M100] TPDD Specifics 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
