To configure the general Linux parameters for SOL operation when using the Red
Hat Enterprise Linux ES 2.1 operating system, complete the following steps.
Note: Hardware flow control prevents character loss during communication over a
serial connection. You must enable it when using a Linux operating system.
1. Add the following line to the end of the
# Run gettys in standard runlevels
section of the /etc/inittab file. This enables hardware flow control and enables
users to log in through the SOL console.
7:2345:respawn:/sbin/agetty -h ttyS1 19200 vt102
2. Add the following line at the bottom of the /etc/securetty file to enable a user to
log in as the root user through the SOL console:
ttyS1
LILO configuration: If you are using LILO, complete the following steps:
1. Modify the /etc/lilo.conf file:
a. Add the following text to the end of the first
default=linux
line:
-Monitor
b. Comment out the
map=/boot/map
line by adding a
#
at the beginning of the
line.
c. Comment out the message=/boot/message line by adding a # at the beginning
of the line.
d. Add the following line before the first
image=
line:
# This will allow you to only Monitor the OS boot via SOL
e. Add the following text to the end of the first label=linux line:
-Monitor
f. Add the following line to the first
image=
section. This enables SOL.
append="console=ttyS1,19200n8 console=tty1"
g. Add the following lines between the two
image=
sections:
# This will allow you to Interact with the OS boot via SOL
image=/boot/vmlinuz-2.4.9-e.12smp
label=linux-Interact
initrd=/boot/initrd-2.4.9-e.12smp.img
read-only
root=/dev/hda6
append="console=tty1 console=ttyS1,19200n8 "
