- *******************************************************************************
- * -NOTE- The Win32 port is a simulation (or is that emulation?) only! Do not
- * expect to get real time behaviour from the Win32 port or this demo
- * application. It is provided as a convenient development and demonstration
- * test bed only. This was tested using Windows XP on a dual core laptop.
- *
- * - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
- * - http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html
- * - Note that the above linked page describes the simulator environment. It
- * - is not the correct page to view for information on using this lwIP demo.
- *******************************************************************************
- *
- * This project demonstrates use of the lwIP stack. The lwIP raw API is
- * demonstrated by a simple http server that comes as part of the lwIP
- * distribution - and executes in the tcpip task. The lwIP sockets API
- * is demonstrated by a simple command line interpreter interface, which
- * executes in its own task.
- *
- * Both the http and command line server can be used to view task stats, and
- * run time stats. Task stats give a snapshot of the state of each task in
- * the system. Run time stats show how much processing time has been allocated
- * to each task. A few of the standard demo tasks are created, just to ensure
- * there is some data to be viewed.
- *
- * Finally, a check timer is created. The check timer is a software timer that
- * inspects the few standard demo tasks that are created to ensure they are
- * executing as expected. It maintains a status string that can be viewed on
- * the "task stats" page served by the web server.
- *
- * More information about this demo, including details of how to set up the
- * network interface, and the command line commands that are available, is
- * available on the documentation page for this demo on the
- * http://www.FreeRTOS.org web site.
