M0 is ignored?

[jrcandy]

Hiya,
Gcode support says M0 is supported but when I have it in the middle of a program it is ignored. I have sent this program via UGS and also chilipeppr with the same result.

The program can be as simple as

G90 G0 X0
M0
G0 X-5

But I wonder how the resume signal would be sent anyway since there's no physical 'resume' button in TinyG board ? It's all good in UGS / chili with their UI, but we'll be sending gcode programatically, so I'm confused how it would resume as there isn't a M-command for 'resume'

Replacing an M0 for a ! in the gcode doesn't work as expected because as soon as it's read that chunk of gcode in the buffer it will stop, not when I want it to stop. Technically M0 is not the same as Feed hold, isn't it?

thanks for your efforts!
