The sio(4) driver can only differentiate between non-FIFO and FIFO hardware (roughly speaking). It cannot differentiate between 16550, 16650, 16750 and/or 16950. > If it helps, I can place this card in a test machine over here for a > couple of days and plug some serial device to it, so that you can play > with it from remote. That may take a day or two to set up however. That would definitely help. If you have a cross-over cable then you can connect both UART interfaces with each other, which makes testing much easier. -- Marcel Moolenaar xcllnt@mac.com
