CentOS - Feb 2010 - Not able to redirect console msgs to serial port

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.
