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.

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

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