PCI RS232 boards

I am trying to get a small cnc machine to work. It uses WINCNC as a
a controller program. The PCI 7200 mother/daughter card has gone
bad. It has two db 25 serial ports outputing to the control box.

My question is this:

Is this PCI board a standard off the shelf board? I'd like to just
get another board and replace it...cheap.

Any one help me out there?


thanks,
