Actually, we took these hacks out in VENIX System V, since, as Rick
pointed out, they didn't work too well, due to problems that
did not appear easily solvable.  Instead, we added
the "ttystate" command, a shell script which (carefully) manipulates
the inittab and turns off and on getty processes.  (I posted this to the net
a while ago.) A uudemon script can use this to disable
the getty before dialing out.  This approach has proved more reliable.
