+// original Written by IVA2K modified LRSD
+// adapted to TestBed card for Electronik laden
+// Example of 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
+// * Static HTM page
+// * Dynamic HTM page a tester
+// LRSD evolution from pub-iva2k-ethsntp project
+// not so good but works.
+// 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
+// in the following items, i put 192.168.1.77
+// 9 Open browser and enter the following URL: http://192,168,1,77 !! ( sd card site)
+// 13 Open browser and enter the following URL: http://192.168.1.77/static.htm
+// 14 The browser will show static HTML page writen in defhtm.h
+// 16 if you clic on Led ( in browser) led5 from testbed light on ou off
+// led change , and the browser is redirected to static.htm
