How can a modem be both "serial" (rs-232) and "internal"

By having a UART on the card and appearing to the computer as a serial
port.  I have several of these in my junkbox (all ISA, though).


Yep, but that's a "controller-based" modem (a PCI card that has the
full components to achieve the modem task, all done by hardware), they
are not called "serial modems". "Serial", in this case, just refers to
the interface.

Those modems (I also had a couple of them back in the day) *are* serial
modems.  There just wasn't a DE-9 connector on them.


I do hope you understand there is a slightly difference between rs-232
and PCI interfaces.

And I hope you understand that "serial" doesn't mean "RS-232".
