title: Closing a COM port with command prompt
body: <p>I need to be able to close COM ports through the command prompt (Windows 7 OS). The reason for this is that I work with a lot of experimental equipment, controlled with a language called LabVIEW, and communication to these devices is sometimes lost. Right now the only fix is to either rename the COM in device manager, or reboot. Ideally I'd like to close the port in command prompt, which I can implement programatically in my control software.</p>
  
  <p>Does anyone know either; how to close a COM port in command prompt, or a quick and easy way of closing a COM port, so then I can reestablish a connection with my device?</p>
  
  <p>Cheers!</p>
