I need help on below php program. as I know this program is use for serial communication. I want to know exactly what is real use of this program. does it configure physical port of PC? if not than What program does ?
Code:
<?php
include 'PhpSerial.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("COM1");

// We can change the baud rate, parity, length, stop bits, flow control
$serial->confBaudRate(2400);$serial->confParity("none");
$serial->confCharacterLength(8);$serial->confStopBits(1);
$serial->confFlowControl("none"); // Then we need to open it$serial->deviceOpen();

// To write into
\$serial->sendMessage("Hello !");
