Where is the infrared port in the PC?

To verify infrared support on a computer

Verify that your computer has an infrared transceiver (the transceiver will appear as a small, dark red window).

If your computer does not have an infrared transceiver, see your manufacturer's documentation to verify whether IrDA functionality is supported.

Open Device Manager in Control Panel.

Double-click Infrared Devices.

If you have an infrared transceiver, but Infrared Devices does not appear in Device Manager, you do not have an infrared device installed.

If no infrared devices are listed, do one or both of the following:

Enter BIOS setup to verify whether the infrared device is enabled in BIOS, in IrDA, or Fast IrDA (FIR) mode. For information about how to enter BIOS setup, see your computer manufacturer's documentation. If the infrared device is disabled in BIOS, you might be able to use your computer's BIOS setup to enable it.

Warning

Using a BIOS setup utility incorrectly can cause your computer to operate incorrectly. Microsoft cannot guarantee that problems resulting from the incorrect use of the BIOS setup can be solved. Use this utility at your own risk. Before you make any changes, make a note of the original settings so that you can reinstate them if necessary.

See your computer manufacturer's documentation to determine whether the BIOS needs to be updated.

Verify that at least one infrared device is listed and that it is enabled.

If infrared devices are listed but they are not enabled, verify that the infrared devices are installed correctly on your computer. For more information, click Related Topics.

Infrared Device For Pc

Well, I've never heard of a phone that uses infrared before. Remote controls use them a lot...but phones usually use bluetooth. Infrared is a "line-of-sight" technology, so usually computers (well, laptops) have the port on the front of the computer near the bottom edge. Sometimes its on the side, but mostly on the front. If you are actually talking about bluetooth, you don't need line-of-sight, you just need to be within the 3-7' range of the device in question. The computer itself will have bluetooth functions to scan for new devices (ie. your phone) or vice-versa.
