Thanks for sharing. I don't have a lot of time to work on my related project right now, but I've been thinking about it a lot. One of the biggest issues I saw when passively sniffing the line between a real S/36 and different terminals is lack of hysteresis in the receiving circuit. Like you, I mode...

Just to elaborate a bit more. There is a ton of information about the Model 11 synchronous serial protocol format in many manuals/sources. However the transport layer and basic command layer is vastly different to TwinAx. The serial/SDLC side of the terminal operation is an early implementation of I...

I'm very interested in this project. I've been working on the problem for some time in reverse. The intent is to create an open-source hardware bridge design from a twin-ax port on a real midrange system (my S/36 in this case) to either a USB terminal emulator or generic TN5250 bridge device. I'm im...
