oh wait,
it sounds like the serial port on the RPi is strictly a console for the PiDP8 while running simH I guess you just ssh to the RPi since you have a network hooked up ?? so then you can run a command line console on your desktop I was thinking to avoid having to keep a spare monitor and keybd just for that just to access the command line console.

Now you got it, Dan. Yes, the serial terminal is under control of the PiDP simulator. Yes, ou can ssh into Linux and work underneath the running Simh. Especially if you are running "headless". AND you can also use the "head" HDMI/USB KBD, to use the command line or even the GUI. GUI, running along with the PiDP8 simulator, maybe runs a little slow with the single core Pi Zero. Its been a while since I did that.
