I'm getting either a Cable or ADSL modem soon. Trying to decide on internal or external. Are all internal cable/ADSL modems stuck using the 16550 UART at 115kps? They hook up to your network card so how does this effect the UART if at all?

Well cable modem isnt using a UART as far as I know. Cable modem works by info coming from the Coax line to the modem, and then to the modem to a Network card.

A UART is a chip on a modem stands for
Universal Asynchronous Receiver Transmitter. Used for serial port interface.

Not to sure on DSL, but I think since the speeds are so high (upwards of 1 megabit) cant use a UART. UART 16550 currenty only support data transfer rates up to 115,200 bps.

Hope I helped out.
