Console does not show login prompt [SOLVED]

[vu Pham]

I added this line

7:2345:respawn:/sbin/mingetty ttyS0

into /etc/inittab
then the login prompt shows up now.

The inittab has lines for tty1 to tty6 only. For some reason, it didn't 
have for ttyS0.

Thanks everybody, and Lonni for making me looking carefully at the ttyS0 
configuration.
