The interface is designed with a combo box (txtPort) which is populated by the RefreshPorts method. This method simply writes the serial port names into the combo box from the list of available ports in Windows. If there are more than 0 ports, select the first one. Whenever you change the selection, the selected COM port is shown in the application title.
The refresh button is intended to refresh the combo box (in case you want to plug another device in, or disconnect one).
When the application attempts to send a serial message, it makes sure that the COM port is open and configured correctly. If the port is already open, the application closes it and opens it with the currently selected configuration (so that you don't have the problem of trying to open a port that is already open or try to open a different port when one is already open ..
When you click on the send button, the application sends the string to the Serial Port.
