The purpose of the app is to control remote hardware like Arduino, Netduino, Raspberry Pi ...
The protocol is TCP/IP (Client).
UP: 0, power, 0
DOWN: 0, -power, 0
LEFT: -power, power, 0
RIGHT: power, power, 0
MIDDLE: 0, 0, 0 or 0, 0, power (Zero active)
Byte Mode: 3 positions are transfered as 3 bytes (default)
ASCII Mode: 3 positions are transfered as text seperated by comma (ended by \n)
Session inactive: Each transmission in a serated connection
Session active: Connection never closed, but if necessary automatic reconnect (default)
Zero inactive: No return to zero values after release
Zero active: Auto return to zero values after release
Sample code for a server on Raspberry Pi:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "unistd.h"
#include "sys/types.h"
#include "sys/socket.h"
#include "netinet/in.h"
