4.4.7 Using the serial port for the Linux console

You can redirect all kernel console messages to the serial port. This can be done
by entering the following command at the elilo prompt or adding it to the elilo.conf
file:
append="console=ttyS0,115200"
You can also redirect not only kernel messages, but any other system message
from the default messages console (which is virtual terminal number 10 on
SUSE LINUX, and /var/log/messages on other Linux distributions) to the serial
port. To do so, you must use the syslog daemon. This daemon controls the flow
of system messages and redirects them wherever we want them to be
redirected. To redirect all syslog messages to the serial port, edit the
/etc/syslog.conf file and add the following string to the line that you want to be
redirected to the serial port:
/dev/ttyS0
Example 4-7 shows an example of this.
Example 4-7 Redirection of kernel messages to the serial port with syslogd daemon
# This is only a part of the /etc/syslog.conf file
# Your file may be different. Here we will send all the kernel
# warning messages to the serial port
kern.warn; /dev/ttyS0
To activate the changes you made in the syslog daemon, enter the command:
/etc/init.d/syslog restart
Refer to the syslog daemon man page for more information about the
configuration.
