我正试图实现下面的代码，我有一个wavecom gsm调制解调器连接到COM6 https://i.stack.imgur.com/yFH8l.jpg它适用于第三方短信网关软件，但它是非常昂贵的。
我得到这些错误
致命错误:未捕获的异常' exception '与消息'无法设置COM端口，检查它是正确的'在C:'wamp'www'sms'index.php第53行(!)异常:无法设置COM端口，请在C:'wamp'www'sms'index.php第53行检查是否正确
我需要做什么才能使它工作?

试试下面的代码，希望能有所帮助，注意:使用php_serial.class.php
代码:<?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();
