first, in lilo.conf:
append="console=ttyS0,38400"
serial=0,38400n8

If you're using GRUB, please see it's documentation, I have no idea.

Then, in /etc/inittab:
T0:23:respawn:/sbin/getty -L ttyS0 38400 vt102

(you should be running 'setserial' to ensure the serial port is
correctly configured).

The above has worked on most of my servers.

You can skip the lilo.conf stuff if you only need a login and don't
need to watch the bootup messages.
