PC Terminal
Although I have a real WY30 teminal, I wanted to use a terminal emulation on my PC to communicate with the NorthStar.
Teraterm works well, BUT it does not support non DEC terminals of the kind old CP/M programs want to see.
Doing some research, commercial terminal emulators for the PC exist but are expensive. In the end I settled for using Kermit - now open source.
As is, it boots up into its own command processor, adding the following lines to the end of K95CUSTOM.INI makes it start as a terminal for the NorthStar. Change com1 to the com port you intend to use on your PC.
set line com1
set carrier-watch off
set speed 9600
set terminal type wy30
connect
