Try using: setserial /dev/ttyS1 port 0x1018, irq 21 I am taking an educated guess at the port number. You can also use setserial to reorder the ports to what you want. Now, this is probably not going to make optimum use of the card. You may want to look at the multi-port options at the end of setserial. As a long shot, you may also see if loading the parport_serial module helps. It helps with PCI serial/parallel card I have to make the serial ports work... You may also want to look into finding a module specific for your card. It is not uncommon for this type of card to have one port that is a register that tells what port generated the interrupt. That way, the driver does not have to check the status of each serial port. I would guess the status port is 0x1010.
