[Simh] exit fig-forth monitor in RST/E

Hi, In RSTS V10.1-L (and possibly others) there is a runtime monitor called FORTH.4TH Fig-Forth v2.0+. If it is installed as a monitor via: install /runtime_system Run-time System: UNSUPP$:FORTH and set as monitor via: set job/key=forth It responds as would a forth REPL: FIG-FORTH V2.0+ 88

I am not able to figure out what devices to enable in SimH PDP-11 to get multiple telnet connections in RSTS/E 9.6. I'm using a PDP-11/73 with 4megs of memory and I have the console configured: SET CONSOLE TELNET=1 I am able to telnet into port 1. It works as a login terminal no
