+/*
+ * example program for TFTPServer class
+ *
+ * How to use:
+ * -> change the IP to something that works for you
+ * -> connect to the mbed with a TFTP client in binary(octet) mode
+ * -> use (s)uspend and (r)esume keys to turn TFTP server on/off
+ * -> upload any file, but .bin files are always put on the internal 
+ *    memory, as are config.txt files
