I hope that you are using the "run level field" in /etc/inittab and the
"telinit" command indirect via your "ttystate" command, becauce that is what it
is should be used for, switching tty lines on and off I mean.

It's the second field in /etc/inittab, and the following arguments serve as
directives to the "telinit" command that changes the run level and what lines
that should be on or off (From the manual) :

0-6	tells "init" to place the system in one of the "run-levels" 0 - 6.
	(one of the diggits 0-6)
a,b,c	tells "init" to process only those /etc/inittab file entries having the
	a, b  or c "run-level" set.
Q,q	tells "init" to re-examine the /etc/inittab file
S,s	tells "init" to enter the single user enviroment. When this level
	change is effected, the the virtual system teletype, "/dev/syscon", is
	change to the terminal from which the command was executed.

(Telinit command is used to direct the actions of "init" and can only be run by
someone who is superuser or a member of group: sys)
