The default configuration (in /etc/remote) for cua00 defines it
to be dialup, requiring a phone number. That phone number
is probably supposed to be defined in /etc/phones.

But for local non-modem connect you want to use "tip tty00" that
uses /dev/tty00, direct connect, no phone number.

I think /dev/tty00 and /dev/cua00 are the same serial port
(the first, known as COM1 in DOS), but there must be some
difference e.g which drivers are used. It might be just
historical name aliases.

Can someone clarify the difference between /dev/tty00 and /dev/cua00?
