They are not Pseudotty's in the Berkeley sense.  A Berkeley PTY has two sides,
the side that looks like a tty to an application, and the control side which
is connected to your communications program like telnetd or mpx or whatever.
The System V SXT devices multiplex multiple "TTY devices" into a single channel
going to a terminal.  You can't divert the backend to a program, it always
goes to the terminal that did the LINK ioctl to pick up the group of pty's.
