[ Disclaimer: I'm no expert. I believe what follows to be the truth, it's
what I've learned and been taught over the years, but it may still be
wrong. ]

The 8250 UART can only operate at up to 19200 bps, good for a modem up to
9600 baud.

The 16450 can only operate at up to 57600 bps, good for modems up to
14.4K.

The 16550 is BROKEN. Don't buy a computer with one.

Tha 16500A is what the 16550 was supposed to be. It operates at up to
115200 bps and suits modems up to 57K.

Anything slower than a 16550A will be a detriment to bandwidth over a
modem, unless your modem is slow anyway.
