console redirection for linux using the grub boot loader

to redirect the console to the serial port and vga console:

during boot, hit a key to stop the automatic boot. scroll down to the line containing the kernel directives. under redhat, this will be the line that starts with the word module. press the e key to edit the line and add the following to the end of the line:

console=ttyS0,9600n8 console=tty

add the parameters to /boot/grub.conf to make the change permanent.
