you can use following code, it works on my gsm modem. its zyxel

<?php

//SMS via GSM Modem - A PHP class to send SMS messages via a GSM modem attached to the computers serial port.

//Windows only (tested on XP with PHP 5.2.6)
//Tested with the EZ863 (Telit GE863) GSM modementer code here
//Requires that PHP has permission to access "COM" system device, and system "mode" command

error_reporting(E_ALL);

//Example

$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->debug = false;
$gsm_send_sms->port = 'COM6';
$gsm_send_sms->baud = 19200;
$gsm_send_sms->init();

$status = $gsm_send_sms->send('09360403533', 'testing 123');
if ($status) {
    echo "Message sent\n";
} else {
    echo "Message not sent\n";
}



$gsm_send_sms->close();
