Yes, you can attach an external modem through the 9-pin serial
port. I've done this a number of times.
There are two advantages for a PCMCIA modem. One - it is smaller,
two it has a 16550 UART chip built in. This allows for faster data
transfers compared to a 8250 UART.
If your notebook computer already has a 16550 UART for its serial port,
you can hook up a 33.6K (or faster) modem to it. If it is using a 8250 UART,
then the external modem can only transfer data reliably up to 9600 Baud or
maybe 14K BAUD at most.
