hi,
i have centos 4.2. 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.
in /proc/ioports
there is entry for that port as
0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0070-007f : rtc 0080-008f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 0376-0376 : ide1 03c0-03df : vga+ 03f6-03f6 : ide0 03f8-03ff : serial(auto) ---- > displayed here 0cf8-0cff : PCI conf1 c000-cfff : PCI Bus #01 c800-c8ff : Realtek Semiconductor Co., Ltd.

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 CentOS 4.2 is nearly 3 years out of date, and with proper updates would be at 4.6 right now.

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?
