As I said, I believe the ESP v1 cards are not treated as "ESP" ports by the driver, and are handled as standard 16550 ports. That's just from reading the code. I don't know of anyone who has actually tried that code on a version 1 card, so you might be the one who needs to tell us. :-) ----------------------------------------------------------------------------- Michael L.
