I'm wrong, I think. I do know that I'm thoroughly confused now. Based on what I
thought I knew.

Ok, gotcha. I thought the UART was the slot itself.

/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
The other two are unknown.
That explains why my eth0 shows up as 0x0300 but doesn't coincide with setserial's
output. (it
doesn't show up with setserial).
What makes a serial device a serial device?? I understand serial and parallel but I
think this
is redefining things.

You hit the nail on the head here. I was assuming that the slots corresponded to the
setserial
entries. Thanks. This clears things up. And explains a lot of my previous confusion.
If it has a UART it is a serial device??? So is there any other standard component
that can have
a UART. I don't have anything else on this system. A couple HDs, eth0, ppp0, monitor,
floppy,
tape, cdrom. If not then one of those setserial entries is my mouse right???
