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

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?
