+/***************************************************
+  Adafruit CC3000 Breakout/Shield TCP Echo Server
+    
+  This is a simple implementation of the echo 
+  protocol, RFC 862 http://tools.ietf.org/html/rfc862 , 
+  for the Arduino platform and Adafruit CC3000 breakout
+  or shield.  This sketch will create a TCP server that 
+  listens by default on port 7 and echos back any data
+  received.  Up to 3 clients can be connected concurrently
+  to the server.  This sketch is meant as an example of how 
+  to write a simple server with the Arduino and CC3000.
+
+  See the CC3000 tutorial on Adafruit's learning system
+  for more information on setting up and using the
+  CC3000:
+    http://learn.adafruit.com/adafruit-cc3000-wifi  
+    
+  Requirements:
+  
+  This sketch requires the Adafruit CC3000 library.  You can
+  download the library from:
+    https://github.com/adafruit/Adafruit_CC3000_Library
+  
+  For information on installing libraries in the Arduino IDE
+  see this page:
+    http://arduino.cc/en/Guide/Libraries
+  
+  Usage:
+    
+  Update the SSID and, if necessary, the CC3000 hardware pin 
+  information below, then run the sketch and check the 
+  output of the serial port.  After connecting to the 
+  wireless network successfully the sketch will output 
+  the IP address of the server and start listening for 
+  connections.  Once listening for connections, connect
+  to the server from your computer  using a telnet client
+  on port 7.  
+           
+  For example on Linux or Mac OSX, if your CC3000 has an
+  IP address 192.168.1.100 you would execute in a command
+  window:
+  
+    telnet 192.168.1.100 7
+           
+  After connecting, notice that as you type input and 
+  press enter to send it the CC3000 will echo back exactly
+  what you typed.  Press ctrl-] and type quit at the prompt 
+  to close the telnet session.
+           
+  On Windows you'll need to download a telnet client.  PuTTY 
+  is a good, free GUI client:
