Introduction
MIport PCI serial interface cards allow you to add RS-232, RS-422 and RS-485
interfaces to Windows based computers equipped with a PCI bus. Depending on your
choice of card one, two or four optically isolated serial ports, or two, four or eight non-
isolated serial ports, can be added. MIport PCI serial cards are Plug and Play
compatible, which allows the Windows Operating System and driver to set the
addresses and IRQ used by the card.
