Serial Port Console Redirection 91
Additional information for editing the grub.conf:
1
You may need to disable GRUB's graphical interface and use the text-based interface instead;
otherwise, the GRUB screen will not be displayed in BMU console redirection. To do so, comment out
the line starting with
splashimage .
2 If you have multiple options in GRUB and you want all of them to start a console session through the
BMU serial connection, add
console=ttyS1,19200 to all options. The preceding example shows
console=ttyS0,19200 added to only the first option.
Enabling Login to the Console After Boot
Edit the file /etc/inittab, as follows:
Add a new line to configure a getty on the COM1 serial port:
co:2345:respawn:/sbin/agetty -h -L 19200 ttyS0 vt100
See the sample file, which shows the addition of 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, <[e-mail]

#
# 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)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
