            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
