In this case a better question might be, why is he using an Internal modem?
OTOH, it sounds as if he might only have one Serial Port and an internal
modem, now that's pathetic!

Still, I use ethernet a lot more than I do serial ports, though I did toss a
8-port DHV-11 (I think that's the right model) in the PDP-11/23+ I put
together last week, along with the ethernet adapter.

Still PC's aren't all bad, I've got a 1Ghz Pentium III that makes a very
nice PDP-10 and PDP-11, I've had TOPS-10, TOPS-20, RT-11, and RSTS/E all
running on it at the same time.
