The Bluetooth Incoming COM Port number is not often used, which is most likely why it was removed as a default setting from Microsoft Windows Mobile 6 and higher. But it is used by a few devices such as the following.

 

 

One of the following methods can be used to enable the BT Incoming COM Port number feature in newer versions of Microsoft Windows Mobile on our rugged handheld computer products.
