body: <p>How to identify which COM ports are connected to BlueTooth from a C# Program?</p>
  
  <p>Here is my requirement. Let us assume the COM ports in my computer are connected to various devices. Let's say we have COM ports 1 through 9, and 2, 3, 4, 5, and 7 are connected at the moment. Now I need to identify, among ports 2, 3, 4, 5 and 7, which ports are connected to BlueTooth devices?</p>
  
  <p>I need to do this using a C# program. Any advice?</p>
