PHP串行端口訪問

Question

我想要實現下面的代碼，我有一個wavecom GSM調制解調器連接到COM6 http://imgur.com/QwkwfMc它工作在第三方短信網關軟件，但它是非常昂貴的。

我得到這些錯誤

Fatal error: Uncaught exception 'Exception' with message 'Unable to setup COM port, check it is correct' in C:\wamp\www\sms\index.php on line 53 (!) Exception: Unable to setup COM port, check it is correct in C:\wamp\www\sms\index.php on line 53

什麼我需要做的，使這項工作？

試試這個下面的代碼希望它幫助， 注：使用php_serial.class.php

代碼：

<?php 


require("php_serial.class.php"); 


$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/ttyS0"); 

// We can change the baud rate, parity, length, stop bits, flow control 
$serial->confBaudRate(9600); 
$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("AT+CMGF=1\n\r"); 
$serial->sendMessage("AT+cmgs=\"+912709345x23\"\n\r"); 
$serial->sendMessage("Hi, This is the sms that I sent to you using PHP script with serial Port communication with my phone as serial device!! GN - VKSALIAN \n\r"); 
$serial->sendMessage(chr(26)); 

//wait for modem to send message 
sleep(7); 


// Or to read from 
$read = $serial->readPort(); 
echo $read; 
// If you want to change the configuration, the device must be closed 
$serial->deviceClose();
