Hi All I am trying to configure GRUB for serial port access for my project. My machine runs on RedHat 9.0 . What I want to do is :: 1. On boot , GRUB should always accept the password from the serial port {ttyS0 }before continuing with booting . 2. I want this without dropping to the console in GRUB. I tried modifying the /boot/grub/grub.conf by adding the following lines :: serial --unit=0 --speed=9600 terminal serial This is not making GRUB go automatically in the serial console . However , if I drop down to the console and then give these commands , then I am able to communicate from another computer using minicom . I want to configure it so that I can make the machine into a monitor-less machine . Any help would be appreciated . Thanks and Regards, Karan Saberwal
