I have the Traub TNS60 working, but I can not send or receive programs, parameters or anything via rs232. I always get errors 860 or 861 I/O error. I used to send programs before, so I know it worked before; the cable and the terminal emulator configuration is the same.
So I think some parameters have to change. I recently loaded the factory parameters via the internal tape reader, so I think something had to change.

Can someone tell me how to do that?

Thank you so much for the help
