hmmm.
i see strange....
this card inserted in my Ultra AXi motherboard.
onboard i have two serial ports:

sab0: <Siemens SAB 82532 v3.2> addr 0x1400400000-0x140040007f irq 43 on ebus0
sabtty0: <ttya> on sab0
sabtty0: console 9600,8,n,1,-
sabtty1: <ttyb> on sab0

ports are worked.

after insert dual-rs232 ports card i have worked sio0 and sio1 (see up).
but in dmesg i see two strange ports:

sio2 addr 0x14003803f8-0x14003803ff irq 41 on ebus0
sio2: type 16550A
sio3 addr 0x14003602f8-0x14003602ff irq 42 on ebus0
sio3: type 16550A

who know, what this?

p.s. sorry for my bad english.
