  This directory contains two executables that demonstrate
  networking with pico]OS. Both programs contain the pico]OS
  realtime operating system and the lwIP TCP/IP stack.

  You may download the lwIP source files and documentation
  from  http://savannah.nongnu.org/projects/lwip/


  "chargen" is a simple demonstration program for lwIP.
  It transfers a character stream in a loop over a socket
  connection, TCP/IP port 19. The data generator is an
  example that comes with lwIP; I have written the data sink
  that receives the character stream and prints it to the
  console. This demo program is not very exciting, it just
  shows how pico]OS and lwIP act together.
  

  "winserver" is a fully featured server demo program for
  MS Windows based host machines and includes

      - a HTTP server    (TCP port 80)
      - a FTP  server    (TCP port 20,21)
      - a chargen server (TCP port 19)

  The program uses lwIP for TCP/IP and the WinPcap driver to get
  access to the MS Windows network environment. This "server"
  can be accessed from everywhere in the local area network that
  is attached to the MS Windows machine.

  To be able to run this demo program you need the WinPcap capture
  driver which you can download at  http://winpcap.polito.it/

  The program installs a RAM disk for HTTP and FTP. The disk is
  initialized with the file driveimg.bin. You can create your own
  RAM disk image with the tool ftpdrive.exe from the pico]OS
  contribution package.

  P.S.:  Don't blame on me when the program crashes or does no
         more respond on HTTP/FTP requests. The lwIP TCP/IP stack
         has still not reached a *very* stable state (v1.1.0).
