I have used the STB com card and gotten all 4 com ports to work with CT (Version 8, haven't tried it with Version 9 yet). When loading the COMTSR, specify the baud rate, I/O address and IRQ and it should work. I think I used IRQ 10 and 12 for COM3 and 4. The Quickpath card sounds like a winner if you can get it to work. 73 Rick Craig N6ND NRaD Code 848 craigr@marlin.nosc.mil
