You immediately lose the flexibility of the serial ports by getting a modem with a fixed address. What's wrong with an external box--they are certainly cheap enough these days. Unless you know which multiport card you want, there is no way of knowing if there will be any conflicts with other hardware. Consensys' multiport card does not use interrupts so it is unlikely there would be a hardware conflict. At any rate, save yourself the worry and get an external modem. Mark T.
