Disconnecting a Serial Port Object

When you no longer need to communicate with the device, you should disconnect it from the serial port object with the fclose function.

• fclose(s)
  

You can examine the Status property to verify that the serial port object and the device are disconnected.

• s.Status
  ans =
  closed
  

After fclose is issued, the serial port associated with s is available. You can now connect another serial port object to it using fopen.
