According to the limitation of number of pararellport's pins . So I would like to use microcontroller co-work with Mach3 through serial port.

I want Mach3 to send command as text to microcontroller and when microcontroller finish each task it will responce back by logic.

But i don't know how to make Mach3 send command through serial port. It will be better if it can do in the G-code program.

So who are have experience in doing this. Help me please.....

Thank you so much
