Many thanks to all for the advice. Unfortunately I'm still not quite there.
I have written an Expect script which runs Simh and sure enough responds to the startup prompts. Unfortunately after it completes the terminal isn't interactive anymore. Oddly it still echoes characters to the screen but with no response - either from RSTS or Rasbian. If I open another Terminal, PS shows me the pdp11 emulator running as another process but tty1 is stuck in bash. I have included a fork and disconnect at the end of the script as suggested but to no effect. Expect commands don't seem to work within Simh. Should they?
