I am doing direct I/O on a parallel port which is fine and necessary for speed. I would like to enumerate the available ports to offer the user a choice of ports at setup time rather than a tedious trawl through device manager to read the address manually. Does anyone know a means of doing this please? Many thanks, Brian
