  10          // Description:
  11          //
  12          //    This example uses HTTP to act as a web server.
  13          //
  14          //    It runs on a C8051F340 connected to a CP2200 via AB4 board.
  15          // 
  16          //    This file contains the main routine, MCU initialization code, and 
  17          //    callback functions used by the TCP/IP Library.
  18          //
  19          // Steps for running this example code:
  20          //
  21          //    1. Replace IP_SRC_ADDR in mn_userconst.h with the desired IP address.
  22          //
  23          //    2. Connect to the C8051F340.
  24          //
  25          //    3. Compile and build the project code.
  26          //
  27          //    4. Download the code to the C8051F340 and press "Go".
  28          //
  29          //    5. Open a web browser on the PC and enter "http:\\XXX.XXX.XXX.XXX"
  30          //       into the URL bar (where XXX.XXX.XXX.XXX is the IP address
  31          //       assigned in Step 1).
  32          //
  33          //    6. The web browser will display a "Hello World" HTML document.
