After I wrote the following, I realized that the gist of it has already
been stated. But here it is. The modem itself has no IRQ or IO address.
Only the serial port that the modem is connected to has an IRQ and IO
address. This is true both for an internal and external modem. But for
an internal modem, it's serial port is located on the same card and
can't be used for anything else except for the modem.
