Hi,
Iam using cento-5.3 on x86 machine and iam working to get the console messages redirected to serial port. I have made the necessary changes in the /etc/inittab file.
- - - - - id:3:initdefault . . so:12345:respawn:/sbin/agetty ttyS0 9600 vt100 - - - -- -
and also in /etc/grub.conf file
- - - - serial --speed=9600 --unit=0 --word=8 --parity=no --stop=1 terminal --timeout=10 serial . . kernel /boot/vmlinux-2.6.18-128.el5 ro root=LABEL=/1 console=ttyS0,9600 - - -
Still Iam not able to see any console messages redirection on serial port.I have connected the serial port of the Machine_1 which has centos running to Machine_2 where i have opened an hyperterminal.I see no console
messages displayed here. Iam , I missing any configuration or is there an rpm i should install ?
Thanks and Regards,

silly question: Have you checked the cable and hyperterm with another device say a managable switch/router?
Is it a cross cable and not 1:1 cable. I have seen people struggle with that sometimes....

dump hyperterm, its horribly annoying to use. recent versions of putty have serial port mode. also, make sure hardware handshaking is disabled, and that the bit rate and format (n-8-1) are correct.

Are you sure ttyS0 is the right one? I do have some machines were i need to use ttyS1 or rarely even ttyS2.
