Both ports are enabled in BIOS with the standard addresses.
OK
ioports gave the info that both ports are there at the right address
02f8-02ff : serial(auto) 03f8-03ff : serial(auto)
No conflicts were visible. Interrupts gave no info about the irq's from the serial ports.
What was the output of that file?

setserial -a /dev/ttyS1
According to the man file, that will report all information about the ports. You will need to try something like this setserial /dev/ttyS1 port 0x2f8 irq 3 Do this as root.
Output with the -v switch (verbose) . Without this switch no info. # setserial -v /dev/ttyS1 port 0x2f8 irq 3 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
lsof just ran without giving any info, meaning I think that it did not see a user.
It did not see any programs trying to attached to the device. Sounds like a configuration file somewhere is not quite right. Others on this list will correct me I'm sure if I am wrong.
Sure ;-)
