A quick reply: On FreeBSD /dev/ttyv0 is the console, and /dev/ttyv[1-8]
are the standard virtual terminals (see /etc/ttys). The client side
of a PTY pair is normally allocated in /dev/ttyp#. To be exact, I have
never had a sufficient number of open PTY pairs in order that the naming
segment "/dev/ttyp#" be exhausted, although nominally it could happen.
The documentation is pty(4). In all evidence kFreeBSD inherits this
naming convention.
