Hi,
I am uing BCB5 Pro & Win98SE/XP
Created an app that uses the parallel port.
I can write to the port, and I can read what was sent.
Problem is if there is a change in status of one of the pins, 
ie. I physically put a pin high, this change is not read.
Is there a command to make the port read the actual values.
Program Im using for ports is from Logix4u.net

Thanks in Advance
Andrew
