Like I have a ratchet Interfacing the Serial / RS232 Port which only unlocks sending a pulse of 5 volts to give it a whirl. The problem is I do not know how to do this pulse using the platform. Till NET or VBA or VBScript. Have enough research on the forums and found nothing that could send this serial pulse through the door
