Doco....

That's that piece of paper, right?

Oops, my fault - like many people it seems I didn't give enough details in the
first place...

It's a jumpered card (not Shrug 'n' Pray), and it's ISA.

We plugged in the card, did a kernel compile with extended serial support, (for
more than 4 ports) and rebooted.  No sign of the ports.  After much hunting
around, we did a mknod to get 4 devices to show up.  So far so hoopy.  Then we
did setserial for each of the ports (like this)
# setserial /dev/ttyS4 irq 15 uart 16550
# setserial /dev/ttyS5 irq 12 uart 16550
# setserial /dev/ttyS6 irq 10 uart 16550
# setserial /dev/ttyS7 irq 9 uart 16550

now, ignoring the obvious IRQ conflicts here, that says that the first port is
COM4 with an IRQ of 14, the second COM5 with IRQ 12 and so on.  Am I right?

This is how the card is jumpered up, and should work as far as I can tell...

That's exactly what I want to do, I just have a ISA card rather than a PCI - no
free PCI slots :(
