kernel /boot/vmlinuz-2.4.9-e.3 ro root=/dev/sda1
initrd /boot/initrd-2.4.9-e.3.img
When you edit the /etc/grub.conf file, follow these
guidelines:
Disable GRUB's graphical interface and use the text-based interface;
otherwise, the GRUB screen is not displayed in console redirection. To
disable the graphical interface, comment out the line starting with
splashimage
.
To start multiple GRUB options to start console sessions through the
serial connection, add the following line to all options:
console=ttyS1,57600
The example
shows
console=ttyS1,57600
added to only
the first option.
Configuring Linux for Server Serial Console Redirection After Boot

Add a new line to configure
agetty
on the COM2 serial port:
co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1
ansi
The following example shows the file with the new line.

# inittab This file describes how the INIT process
# should set up the system in a certain
# run-level.

# Author: Miquel van Smoorenburg
# Modified for RHS Linux by Marc Ewing and

#
# Default runlevel. The runlevels used by RHS are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you
# do not have networking)
