I don't know how enable infrared port in my pc - ibm thinkpad x 41

By default, currently available ThinkPads come with the external serial port disabled and Infrared enabled on COM1. To use the serial port on COM1 you must either disable infrared or change infrared so that it uses alternate resources. If you are not using infrared for printing or file sharing it is recommended that it be disabled. Here are the steps to follow to enable infrared :

1. Double-click your ThinkPad Features or ThinkPad Configuration icon located in the ThinkPad folder on your desktop.

2. Locate the Infrared button located on the left-hand side of this configuration screen and click it once. (Note: If you hold your mouse pointer over any of the icons in this configuration screen the button will be identified at the bottom in the status window.)

3. Change Infrared from "Disable" to "Enable" and click "OK".
4. Locate the serial port icon and click it once.
5. Select serial port "enable" and insure that the COM PORT setting is "COM 1" and click "OK".
6. Shut down and restart the computer.
