Via Epia Nano ITX and Mini pci serial port

[r52gm1]

Hi Guys, Gals and other sexes.
I am very new to Linux and would appreciate some assistance with my problem.

I had a small bespoke computer running vine linux 2.4 that used to run an embedded program to control my Ham radio.
The board self destructed.
I replaced the MB with a Via Epia nano Itx MB.
The machine works well with any OS, but it had no serial ports to communicate with the radio.
I then fitted a mini Pci quad serial board which works well with windows OS.
The board uses an Oxford quad 16940 UART .
How can i get the Linux OS to address this board simply.
The bespoke embedded OS works up to the point where it needs an echo from the radio via the serial port and then just sits there with a blank screen.
I am very new to Linux

HELP!!!!

Thanks in anticipation.
Bob

At a rough guess, I'd say it's a problem connecting to the correct serial port.
Have a look at the boot messages and see if the com ports are recognised and then set the program to use the correct one.
Being an add on board, it could also be an irq problem that you need to set for manually your older linux system.

the boot message says it sees ttys04 to 6 id do not know how to redirect ttys0 to ttyso4 can you help?

OK, ttyso4 corresponds to serial port 4 or com4, with interrupt 4.
Since you have and old linux, it is probably set up to look at serial 1 or 2.
Try changing the connector to each of the other free connectors on the card and see if it works.
If not, there must be some sort of setup with the connection program that allows you to choos/set the comm port parameters.
