Is it possible to set a digital input true via gcode?
I know I can M66 wait for input, but I want to set it true.

Sounds like you want a digital output M62-M65.
linuxcnc.org/docs/html/gcode/m-code.html#mcode:m62-m65
You'd then connect the digital output pins (motion.digital-out-00...) to what ever inputs you need to change in hal.

I am trying to set iocontrol.0.tool-change to true. It is an out bit.
Not in HAL, need to use gcode so I can put it in a function in a remap.

nevermind. its in the epilog, self.tool_change_flag = True

its not getting to task though.

I am sure that this can't be the "right" way, and in fact might not even work, but have you tried command.mdi("m6") in the remap?
