【问题描述】：
我正在使用 GPRS MODEM 使用带有this device 的 php 发送短信。
我使用 AT Tester 尝试了我的设备，以确定我的设备是否运行良好并成功发送。
然后我尝试了这个使用 PHP 通过 GPRS 调制解调器发送短信的链接：https://www.sitepoint.com/community/t/send-sms-using-gsm-modem/28584。
这是提供的代码：
<?php
//Example
error_reporting(E_ALL);
//Example
$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->debug = true;
$gsm_send_sms->port = 'COM4';
$gsm_send_sms->baud = 9600;
$gsm_send_sms->init();
$status = $gsm_send_sms->send('+639153380630', 'testing 123');
if ($status) {
echo "Message sent\
";
} else {
echo "Message not sent\
";
}
$gsm_send_sms->close();
//Send SMS via serial SMS modem
class gsm_send_sms {
public $port = 'COM4';
public $baud = 9600;
public $debug = true;
private $fp;
private $buffer;
//Setup COM port
public function init() {
$this->debugmsg("Setting up port: \"{$this->port} @ \"{$this->baud}\" baud");
exec("MODE {$this->port}: BAUD={$this->baud} PARITY=N DATA=8 STOP=1", $output, $retval);
if ($retval != 0) {
throw new Exception('Unable to setup COM port, check it is correct');
}
$this->debugmsg(implode("\n", $output));
$this->debugmsg("Opening port");
//Open COM port
$this->fp = fopen($this->port . ':', 'r+');
//Check port opened
if (!$this->fp) {
throw new Exception("Unable to open port \"{$this->port}\"");
}
$this->debugmsg("Port opened");
$this->debugmsg("Checking for responce from modem");
//Check modem connected
fputs($this->fp, "AT\r");
//Wait for ok
$status = $this->wait_reply("OK\r\n", 5);
if (!$status) {
throw new Exception('Did not receive responce from modem');
}
$this->debugmsg('Modem connected');
//Set modem to SMS text mode
$this->debugmsg('Setting text mode');
fputs($this->fp, "AT+CMGF=1\r");
$status = $this->wait_reply("OK\r\n", 5);
if (!$status) {
throw new Exception('Unable to set text mode');
}
$this->debugmsg('Text mode set');
}
//Wait for reply from modem
private function wait_reply($expected_result, $timeout) {
$this->debugmsg("Waiting {$timeout} seconds for expected result");
//Clear buffer
$this->buffer = '';
//Set timeout
$timeoutat = time() + $timeout;
//Loop until timeout reached (or expected result found)
do {
$this->debugmsg('Now: ' . time() . ", Timeout at: {$timeoutat}");
$buffer = fread($this->fp, 1024);
$this->buffer .= $buffer;
usleep(200000);//0.2 sec
$this->debugmsg("Received: {$buffer}");
//Check if received expected responce
if (preg_match('/'.preg_quote($expected_result, '/').'$/', $this->buffer)) {
$this->debugmsg('Found match');
return true;
//break;
} else if (preg_match('/\+CMS ERROR\:\ \d{1,3}\r\n$/', $this->buffer)) {
return false;
}
} while ($timeoutat > time());
$this->debugmsg('Timed out');
return false;
}
//Print debug messages
private function debugmsg($message) {
if ($this->debug == true) {
$message = preg_replace("%[^\040-\176\n\t]%", '', $message);
echo $message . "\n";
}
}
//Close port
public function close() {
$this->debugmsg('Closing port');
fclose($this->fp);
}
//Send message
public function send($tel, $message) {
//Filter tel
$tel = preg_replace("%[^0-9\+]%", '', $tel);
//Filter message text
$message = preg_replace("%[^\040-\176\r\n\t]%", '', $message);
$this->debugmsg("Sending message \"{$message}\" to \"{$tel}\"");
//Start sending of message
fputs($this->fp, "AT+CMGS=\"{$tel}\"\r");
//Wait for confirmation
$status = $this->wait_reply("\r\n> ", 5);
if (!$status) {
//throw new Exception('Did not receive confirmation from modem');
$this->debugmsg('Did not receive confirmation from modem');
return false;
}
//Send message text
fputs($this->fp, $message);
//Send message finished indicator
fputs($this->fp, chr(26));
//Wait for confirmation
$status = $this->wait_reply("OK\r\n", 180);
if (!$status) {
//throw new Exception('Did not receive confirmation of messgage sent');
$this->debugmsg('Did not receive confirmation of messgage sent');
return false;
}
$this->debugmsg("Message sent");
return true;
}
}
?>
执行代码后，PHP 返回此错误：

【问题讨论】：
-
您是否尝试通过任何其他 PC 软件（某种形式的终端仿真器）连接到它。
-
@NigelRen 是的，我尝试过使用 AT Tester，它成功发送了一条消息。
-
我只能建议使用 AT Tester 并使用一些东西来检查端口设置，看看您配置端口的方式是否有任何差异。
-
@Nigel。代码中是否有任何错误或其全部在端口配置中？。
-
能否请您在不同的行中发布包含不同消息的日志结果？目前不可读。此外，尚不清楚您使用的调制解调器型号：您提供的链接会指向谷歌图片搜索页面。最后：responce -> response.
