To check the ports used for infrared communication:

1.In the Windows taskbar, click Start.

2.Choose Settings, and then choose Control Panel.

3.Double-click Infrared.

4.Click the Options tab.

5.Select Enable infrared communication.

The COM port displayed in the drop-down box is the same port to which your infrared device is attached. It should be different from any port that is used by the HotSync Manager.

6.Make a note of which port is listed as “providing application support.” You need this information to configure the HotSync Manager for infrared communication.

This port (COM4 in this example) is the simulated port, the channel through which the actual infrared communication takes place between your personal computer and your hand- held computer.

7.Deselect any other check boxes in the Options tab.

8.Click Apply and OK.
