+//  server v4 ou version 4   modified LRSD  
+//  for mbed with  TestBed  card  Electronik laden
+// Example d' HTTPServer 
+// * SNTP Client (Simple NTP)
+// * Link status indication (LED4 or RJ45 socket LED on MBED-BoB2-mod)
+// * Local file system 
+// * SD-based WebServer ,  sd card 128meg only **.htm  8.3
+//  LRSD  evolution from    pub-iva2k-ethsntp  project
+// Instructions:
+// 1  Plug ETH connector into your network (with a switch beetwen   pc)
+// 3  Plug MBED tu pc  using USB cable
+// 4  need to have Installed MBED serial driver (http://mbed.org/handbook/SerialPC)
+// 5     Copy compiled .bin to your MBED (make sure target device selected in the compiler is correct)
+// 6  Open terminal on the mbed serial port
+// 7  Push MBED reset button
+// 8  Terminal will display info message with mac address, followed by IP address 
+// 9  Open browser and enter the following URL:    http://192,168,1,77/   !! ( sd card site)
+// 10 The browser will show "index.htm"  web page that you put in the sd card
+// 11 Open browser and enter the following URL:  http://192,168,1,77/testbed.htm  
+// 12 here in  your browser     clic on Led  on ou off  !!
+// 13               or  Lecture , an1.htm in sd  show a voltage in testbed ( pot)
+// 14               or put a number and envoyer , give a number to testbed card     
+// les fichiers htm utiles a mettre en SD sont dans le r'epertoire htm.
