Disable login in tty0


I do not want any output on the DVI port. So I added
dmesg -n 1
to /etc/rc.local and have not debug output anymore. But I am see the login screen. So I changed somel lines containing tty in /etc/inittab:

root@beaglebone:/home/debian/Server# grep tty /etc/inittab
#1:2345:respawn:/sbin/getty 38400 tty1

2:23:respawn:/sbin/getty 38400 tty2
3:23:respawn:/sbin/getty 38400 tty3
4:23:respawn:/sbin/getty 38400 tty4
5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6

T0:23:respawn:/sbin/getty -L ttyO0 115200 vt102

But I still see the login prompt. What else I have to do to completly disable all output on ttyS0? Or is it not ttyS0?

Background: I use this console for my own output to DVI monitor using libdrm.
