====== Controlling Grub through serial link ======

With this configuration of Grub I can boot my box and control the boot menu, make choice's, and see the output from the boot sequence.


===== /boot/grub/menu.lst =====

<file>
#color white/blue black/light-gray
default 0
timeout 3
#gfxmenu (hd0,0)/message

serial --unit=0 --speed=9600
terminal --timeout=15 console serial
