This is the I/O card.

The first thing you probably need is the parport_serial modual. When
you modprobe this modula, it may or may not create the serial ports
you need. I am using one on a Mandriva system, and at one time it
would set up the serial ports as well, but this no longer works for
me. I have to use setserial to set them up now. The other thing to
be aware of is that the ports may be /dev/ttyS4 and /dev/ttyS5.
Ports /dev/ttyS0 through /dev/ttyS3 are usually reserved for the
onboard serial ports. I am not sure how it would be handled in your
case.
If you have to set the ports up by hand, you will need to run
"lspic -v" to get the port numbers and IRQ. You should see something
like this:
02:0a.0 Communication controller: NetMos Technology PCI 9835
Multi-I/O Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic 1P2S
Flags: medium devsel, IRQ 21
I/O ports at 1090 [size=8]
I/O ports at 1098 [size=8]
I/O ports at 10a0 [size=8]
I/O ports at 10a8 [size=8]
I/O ports at 10b0 [size=8]
I/O ports at 1080 [size=16]
The first 2 ports are the serial ports. What I did was create a file
/etc/rc.d/rc.serial that looks like this:
#!/bin/bash
#
#Configure extra serial ports.
#
/bin/setserial /dev/ttyS2 uart 16550A port 0x1090 irq 21 baud_base
115200 spd_normal
/bin/setserial /dev/ttyS3 uart 16550A port 0x1098 irq 21 baud_base
115200 spd_normal
If you have to go this route, you will probably want to use ttyS0
and ttyS1 instead of ttyS2 and ttyS3.
