Does SCO UNIX have job control?

I believe that the SCO Unix kernel supports job control, but the
shells (sh and csh) provided with their release 3.2.0 do not support
it. The following is excerpted from /usr/include/sys/signal.h
# define SIGSTOP 23 /* sendable stop signal not from tty */
# define SIGTSTP 24 /* stop signal from tty */
# define SIGCONT 25 /* continue a stopped process */
# define SIGTTIN 26 /* to readers pgrp upon background tty read */
# define SIGTTOU 27 /* like TTIN for output if (tp->t_local&TOSTOP) */
So the development system, at least, seems to believe that signals are
available.
