Re: Retrieve the keys pressed on a Display file

["Gene Burns" <burns.gene@xxxxxxxxx>]

Clear does return an AID byte, but Home does not.

Does anyone know what the Forward Edge Trigger Auto Enter is used for, or
what causes it?
What about PA1 (hex 50), PA2 (hex 6E), and PA3 (hex 6B)?

I have not found an explanation of these AID bytes.
