I have tried to cat /dev/ttyS5 after

setserial /dev/ttyS5 port 0xd800 irq 11

[ I tried 0xd400 and 0xd800] and everything went to

cat: /dev/ttyS5: Input/output error

So, maybe this card is not 8250 compatible :-(

The card has one region of size 128:

	Region 1: I/O ports at d400 [size=128]

I think that it is EEPROM, because there is a driver for EEPROM on this PLX
chip somewhere on the Internet (I do not have that link here).

I think I started with hitting C-h a lot.  Really a LOT.
