Agreed, for the most part. The particular internal modem I've 
been using for a couple of years now (a USR Sportster 33.6) has
its own UARTS, and for good reason -- at least on the system
I used to run it on (PB) before I upgraded. The PB only had the
cheaper UARTs (i.e., not the 16550) and worse, they were
soldered on to the main board.

So in that particular instance it made sense to get a new
internal modem, since it had the newer 16550A UARTS with the
bigger buffers.

By the way, on that particular machine, Linux was able to
service the serial port (no 16550) at full 9600 bps speed;
Windows could not. I guess I'm glad we didn't have winmodems
back then :).

Definitely - at least nowadays.
