To include from termio.4 under SunOS4.0.1:
The controlling terminal is inherited by a child process
during a fork(2). A process relinquishes its control termi-
nal when it changes its process group using setpgrp(2V) or
when it issues a TIOCNOTTY ioctl(2) call on a file descrip-
tor created by opening the file /dev/tty.
This is a hybrid of the BSD and System V functionality.
