I try to use OXmPCI954-LQAG(UART 16PCI954) 4 serial port PCI card.
I connected barcode scanner to it but it does't work, when I try to read from it like
cat /dev/ttyS1
don't recieve anything, but in minicom when change bodreate to 9600 I have many "?".
On internal serial port /dev/ttyS0 I recieved all rights.
setserial -a show same configurations for /dev/ttyS0 and /dev/ttyS1.

I try diferent linux distributives, but no one works fine.
Does it have wrong drivers in kernel(module)?
What can I do with it to try something else?

Somebody try it?

P/S Sorry for my English...

Sounds like you've got the wrong baud rate/stop bits/parity, since you're getting garbage via Minicom. Check out the setserial command, too.
