I am also doing the same to configure the serial console on centos 5.4.

But my problem is that my computer ttyS0 (com1) is not working. I installed a PCI serial card & it is installed in Centos as ttyS1.

Now i want to do the same with ttyS1, my grub.conf is as follows:
**********************************************
default=0
timeout=5
#splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
serial –unit=1 –speed=115200
terminal –timeout=2 console serial
title CentOS (2.6.18-164.15.1.el5.centos.plusPAE)
root (hd0,0)
kernel /vmlinuz-2.6.18-164.15.1.el5.centos.plusPAE ro root=/dev/CoralVol00/CoralOS00 console=tty0 console=ttyS1,115200n8
initrd /initrd-2.6.18-164.15.1.el5.centos.plusPAE.img
title CentOS-base (2.6.18-164.15.1.el5.centos.plus)
root (hd0,0)
kernel /vmlinuz-2.6.18-164.15.1.el5.centos.plus ro root=/dev/CoralVol00/CoralOS00 rhgb quiet
initrd /initrd-2.6.18-164.15.1.el5.centos.plus.img
**********************************************

I also created an entry in inittab:
**********************************************
S1:12345:respawn:/sbin/agetty -L 115200 ttyS1 vt100
**********************************************

But i am receiving kernel panic after doing these setting. Can you help me, what i am doing wrong?

Regards,
Rahul Panwar

I use it to have serial console in my VMware server lab servers :) This also works with almost all linux distros, except that a few distros already have ttyS0 in the /etc/securetty file (at least Debian and its sons).
