<ul></ul>This demonstration shows another method of performing control and status reporting. This time, we use Server Side Include tags to replace text in the page as it is being server from the Tiva C Series DK board and standard HTML forms to send data to a CGI handler
running on the board. This example does cause the page to be reloaded whenever form data is submitted but it involves less complex HTML to perform the task.
