The command: 'man inittab' on a system with sysv installed will give
you all the gory details, but...

If you want the above to happen in all levels except 0 & 6 :
1:12345:respawn:/sbin/getty 38400 tty1
2:12345:respawn:/sbin/getty 38400 tty2

Other examples in the man(ual), such as how to use the S&K scripts.
If you don't have a system with the sysvinit manual installed,
Google can find you a copy posted on the web.
