For AT&T SysV 3.2.3, a simple:
shutdown -y -g0 -i6
will reboot the system.  'g' being the grace period before shutdown starts.

If you want to do it remotely or on another terminal, copy /etc/shutdown
to say /etc/shutdown2, strip out the portion that checks that you are
on /dev/console.  Then do
shutdown2 -y -g0 -i6

This gives you shutdown with reboot on any port (as long as you are 'su').
