我正在使用诺基亚USB设备和PHP脚本发送短信但收到错误 堆栈上有很多答案，但没有答案可以解决这个问题
Fatal error: Uncaught Exception: Unable to setup COM port, check it is correct in C:\xampp\htdocs\sms-prac\send-sms.php:103

我用来发送短信的PHP代码
<?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 modem
//Requires that PHP has permission to access "COM" system device, and system "mode" command
ini_set('max_execution_time', 300);
error_reporting(E_ALL);
//Example
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "MembersManagmentSystem";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT Member.memberId, Member.memberContactMobileNumber, SMSRecipient.smsRecipientReceiverId, SMSRecipient.smsInfoId, SMSInfo.smsInfoText, SMSInfo.`smsInfoSaveDateTime` FROM Member, SMSRecipient,SMSInfo WHERE SMSRecipient.`smsRecipientReceiverId` = Member.`memberId` AND SMSRecipient.`smsInfoId`= SMSInfo.`smsInfoId` AND SMSRecipient.smsRecipientSentDateTime IS NULL AND Member.`memberContactMobileNumber` IS NOT NULL AND SMSInfo.`smsInfoSaveDateTime` > DATE_SUB(NOW(), INTERVAL 1 DAY)";
$result = $conn->query($sql);
echo "<pre>";
$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->debug = false;
$gsm_send_sms->port = 'COM3';
$gsm_send_sms->baud = 115200;
$gsm_send_sms->init();
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
print_r($row);
$status = $gsm_send_sms->send($row['memberContactMobileNumber'], $row['smsInfoText']);
if ($status) {
$sql = "UPDATE SMSRecipient SET smsRecipientSentDateTime = now() WHERE smsInfoId = ".$row['smsInfoId']." and smsRecipientReceiverId = ".$row['memberId'];
if ($conn->query($sql) === TRUE) {
echo "Message sent\n";
}
} else {
echo "Message not sent\n";
}
}
//exit();
} else {
echo "0 results";
}
$gsm_send_sms->close();
$conn->close();
?>
更改$ gsm_send_sms-＆gt; debug = false;为了真实，得到
Array

在上面的代码调试之后，我发现当我第一次连接我的设备并运行它时php执行此行就像无限循环一样，在此行之前所有debugmsg和其他代码运行良好请帮助我
$buffer = fread($this->fp, 8192);
