+// original Written by IVA2K
+//
+// Example of HTTPServer with additional features:
+// * SNTP Client (Simple NTP)
+// * Link status indication (LED4 or RJ45 socket LED on MBED-BoB2-mod)
+// * Local file system (create index.htm page on MBED!)
+// * SD-based WebServer
+// * Static HTML page
+// * Dynamic HTML page
+// modification fron LRSD from the pub-iva2k-ethsntp project
+// i am not a specialist , stil bugs , but that works
+// Instructions:
+// 2 Plug ETH connector into your network(with a switch for direct pc, needs DHCP to get IP address and Internet connection)
+// 3 Plug MBED 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 line 144 : IPv4(192,168,1,77),
+// 9 Open browser and enter the following URL:
+// http://192,168,1,77 /
+// !!
+// 13 Open browser and enter the following URL:
+// http://192.168.1.77/static.htm
+// 14 The browser will show static HTML page
+// 15 Open browser and enter the following URL:
+// http://192,168,1,77/dynamic.htm
+// 16 The browser will show dynamic HTML page
+// 17 Create a simple index.htm page on the MBED
+// 18 Open browser and enter the following URL:
+// http://192,168,1,77
+// 19 The browser will show index HTM page not HTML! ( 3 char extension , no directorie)
+// 20 Create a simple index.htm page on a micro SD card, plug the card into MBED-BoB2
+// 22 The browser will show index HTM page from SD card
+// 23 Optionally, create file "sntp.ini" on MBED or SD card. Copy-paste SNTP configuration from the terminal into this file and modify to your needs.
