Hello Now i am trying a program but ubuntu sent message but it is not my message for me

example php

<?php include "php_serial.class.php"; // Let's start the class $serial = new phpSerial; // First we must specify the device. This works on both linux and windows (if // your linux serial device is /dev/ttyS0 for COM1, etc) $serial->deviceSet("/dev/ttyUSB0"); //Set the serial port parameters. $serial->confBaudRate(9600); $serial->confParity("none"); $serial->confCharacterLength(8); //Character length $serial->confStopBits(1); $serial->confFlowControl("none"); // Then we need to open it $serial->deviceOpen(); $serial->sendMessage(chr("0")); $serial->deviceClose(); // We can change the baud rate //$serial->confBaudRate(9600); // etc... ?>
