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. hank White Oak Software Inc.
