 Is it possible to set that I will see only present and free serial ports in nrDeviceBox1 list.
Now I see in nrDeviceBox1 list of all connected ports, including used ones by some other applications.
When I try to open used port I get message for example "Device "COM4" Open Error !!!!"
Can you please help me how to solve this problem.

You need to try open every visible ports, handle possible exceptions and fill ordinary TComboBox control by com ports with no exception.
TnrDeviceBox does not provide such functionality. Sorry.
