Introduction

The 3PCI2 Dual Port serial interface card is designed to work with
Windows based IBM compatible computers with a PCI bus. The card
is Plug and Play compatible which permits the Windows Operating
System and driver to set the addresses and IRQ used by the card.
If you are developing your own software, make sure that the
communications routines support Windows communication drivers
and a wide range of COM ports (Com1 to Com16 or higher).
