Okay, your first task is to run 'yum update' immediately. CentOS 4.2
is nearly 3 years out of date, and with proper updates would be at 4.6
right now.

I have install a PCI card having serial port.

What are you using to talk to the serial port. How are you attempting
to use it?

You're telling us there's a problem but you're not telling us what the
problem is.

Are you sure you're using the right /dev/ttyS* value for the port?
What are you connecting to the port that's not communicating properly?

What errors are you getting with what you're trying to do?
