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 CentOS 4.2 is nearly 3 years out of date, and with proper updates would be at 4.6 right now.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.
when the os is booted it detects the new hardware ( serial port) .a device is also created /dev/ttyS0. the port works very goog on the same pc in windows XP. but when i connect any serial device to that port in linux it does not work.
What are you using to talk to the serial port. How are you attempting to use it?
please help me out is there any extra configuration to be done.
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?
