The PCI-485 uses standard 16550 UARTs, and while there isn't a packaged DOS driver avilable, you should be able to use the card in DOS applications by configuring the software to use the base address assigned to the UART that you wish to use. One important note is the RS-485 wire modes which are configured via the scratch register. The user manual documents how this is performed.

Addendum to Chris' note: However, if you require hardware interrupts you will need to configure the AMCC chip on the board. "ni.com" has an "NI-Serial for Linux/Intel x86" page with a tar (compressed) package which has useful documentation and source code (albeit for Linux) that address board set-up (including interrupts).
