I assigned /dev/ttyS2, but didn't worked

when I do cat /proc/ioports, I get:

it doesn't show something releated to IRQ 10, I have:

when I do cat /proc/pci I get:
Bus 0, device 10, function 0:

Vendor id=127a. Device id=2015.

ok I typed it and got:
[root@megatron /root]# setserial /dev/ttyS12 irq 10 port 0xe400
/dev/ttyS12: Operation not supported by device
[root@megatron /root]#
Previously I typed: mknod --mode=644 ttyS12 c 4 68

I couldn't do that because first we have to get the /dev/ttyS* running,
I'm wrong?

sniff... it doesn't works. :-(

ok, I have:
Make: Maxsenger (?)
Model: DM-56V14HSF/2
Manufacturer: Aceex Corp.
FCC: I can't find it, but maybe it's: 98100028767, it also has bar codes.
by the way, I have to modify something in my BIOS configuration?
Thanks
