FORPCheck Checks if a button of a FORP device (HH-5-CYL) is pressed.


[KeyPressed,EventTime] = FORPCheck()

Return the key name (KeyPressed) of the pressed button and the
time (EventTime) of the status check.

KeyPressed Key name of the Pressed Button, empty string
if none pressed.

EventTime Time of keypress check, as returned by GetSecs.


See FORPWait.

Going through each device can be very time consuming. If would advise
to unplug each unnecessary device, so less devices has to be checked.
If you have got any advice for a better way to solve those problems, feel
free to let me know:
