MDI command on halcomp

Hi.
Are there any way to send such instruction from hal compenent like python?

self.mdi("G0 X100")

Regars.

You can do it from a Python HAL component.
linuxcnc.org/docs/stable/html/hal/halmodule.html
You can't do it from a C realtime component AFAIK, though a C component could set a pin that runs an MDI_COMMAND
linuxcnc.org/docs/stable/html/config/ini....html#_halui_section
However, given that halui runs in userspace there is no reason to prefer this over the userspace HAL component.
