What steps will reproduce the problem?
1. run xampp on windows
2. select COM13 (or com port you want)
3. run it with this script below.

<?php
include "php_serial.class.php";

echo "<html>
      <head><title>Test MySQL</title></head>
      <body>";


// 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("COM13");

$serial->confBaudRate(9600);

// Then we need to open it
$serial->deviceOpen();

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

// Or to read from
$read = $serial->readPort();

echo "here it is";
echo $read;
echo "here it was";


sleep(1);

// If you want to change the configuration, the device must be closed
$serial->deviceClose();



// We can change the baud rate
//$serial->confBaudRate(2400);

// etc...
?>
</body></html>

I had finally solved it. All you need to do is change the com port to anything 
between 1 and 5.

In php_serial.class.php, for COM > 4, change at OS Windows:
$this->_device = "\\.\com" . $matches[1]; 
with 
$this->_device = "\\\.\com" . $matches[1];

I used this:


// If you are using Windows, make sure you disable FIFO from the modem's
// Device Manager properties pane (Advanced >> Advanced Port Settings...)
