OK, again just to clarify...my micro is hooked to a host at 9600. I will reconnect the detector directly to a 8255, can't change that...just the way my board is built. I will write a program in assembly to produce a buffer in the higher memory addresses. if a key is presses on the remote then it will start to fill the buffer, when released it will send the recorded data to the host terminal correct?..I want to add sometype of decision structure so the controller knows what button is being pressed but I can add that later..
if I am missing anything please tell me I have been working on this for about 3 weeks now and an advancement would be great...I will ask again to be sure, I could not use basic? using this buffer idea?
