[Simh] DZ issues on PDP10

[Quentin North]

Hi

There has been quite a bit of chat about the DZ handler recently, so I just wanted to share an issue that I have found whilst using a DZ mux on pdp10. When I have more than one terminal connected, intermittently i/o on one terminal stop until there is i/o on another terminal (usually me pressing return). I haven’t identified any cause but if I experience it again is there any diagnostics I can do to help pin it down?

First, please use the latest github code.
Second, if you see something like that, use CTRL-E and SHOW MUX to help
understand what's happening. If you see a problem please create an issue
at https://github.com/simh/simh/issues.

Thanks.
