";
    $data .= "ID_TERMINAL: ".$atm_id."
";
    $data .= "NRO_TRANSACCION: 123456
";
    // Create socket
    $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket
");
    // Connect to the server
    $result = socket_connect($socket, $host, $port) or die("Could not connect toserver
");
    // Write to server socket
    socket_write($socket, $data, strlen($data)) or die("Could not send data to server
");
    // Read the response from the server
    $result = socket_read ($socket, 1024) or die("Could not read server response
");
    echo "Reply From Server  :".$result;
    // Close the socket
    socket_close($socket);
