If you open up the Show HAL Configuration window then add your output pins to a watch window you can see if EMC is changing the state of a pin. You can also set a pin that is not being used with hal command. In the SHOW window if a pin is connected it will show up like this "parport.0.pin-01-out <== estop out". The "<== estop out" is the signal that the pin is connected to. To unlink a pin use "unlinkp parport.0.pin-01-out" in the Test HAL command box. Then to set the pin on use "setp parport.0.pin-01-out 1" and 0 for off.
