Doesn't work while in FOR loop

For that matter nor does a damn M108 sent to terminal. Printer ignores all but a M112 direct to terminal or through USB keyboard while in the sacred non-interuptable for loop that ABL uses. Poorly coded - the ABL, not your software. 

It should of stopped it though since M112 from terminal worked.  It stopped after the ABL was done. I use 7^2 points. Why use 9?
