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?
