title: Change properties in device manager
body: <p>i am working with serial device, i want to communicate my computer with microcontroller. In my C# program, i can set the baud rate, stop bits, data bits etc. These just in my C# program. </p>
  
  <p>For example, i set the baud rate 115200 in microcontroller and my C# program, But when i see the properties of my device in device manager, the baud rate is still using default, 9600 bps. I don't know if it is good or no for communication, my C# program and microcontroller using 115200bps, and in the properties using 9600bps, but the communication is working.</p>
  
  <p>How to change the properties of device in device manager?</p>
