Tormach Mill Simulation (770MX): No Way to Take Out of E-Stop

I just installed the default LinuxCNC Debian 12 to a dedicated desktop PC. There is a Tormach 770 PNC configuration available without anything special, and I've loaded that (though I am working with a 770MX, it is not connected to this computer). I am not a machinist, and I know very little about LinuxCNC, although the Tormach PathPilot is derived from LinuxCNC. From what I can tell the 770 PCNC configuration should work, and it sort of does. I can load a simple g-code file which I've used on the 770MX, and it shows the same graphical display as the actual 770MX (I also imported the tool table from the actual Tormach). The problem: There is no way to "run" the code.

I'm attaching a screenshot. You can see it is in E-Stop, and the buttons I think are for starting cycle (which is unclear if those are for that purpose) are grayed out. Menus do not have any way to take this out of E-Stop or reset. Maybe there is some added setup needed for this to be a simulation without hardware? Any suggestions on what to look at to make this run like a PCNC 770 from Tormach?
 

This is entirely for simulation. I'd like to see how things work on the simulation prior to putting g-code onto the actual Tormach. It makes experimentation safe.

So far I have used the provided files which come with the LinuxCNC install:
~/linuxcnc/configs/by_machine.tormach/pcnc-770.*

It sounds like "~/linuxcnc/configs/by_machine.tormach/pcnc-770.ini" is where to look. I'll dig around in that and see if I can see what you are mentioning. Thank you!

PS: That file is a copy from the reference copy already, but I will make a backup anyway.
