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
Edit the file /etc/inittab, as follows:
• 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.
