我有一个菜鸟问题 - 我创建了一个非常简单的 HTML 页面，当按下按钮时，通过我的网络将一串串行数据发送到以太网到串行转换器。这控制音频矩阵开关（通过其串行端口）。该网页可以工作并且它会切换音频矩阵，但是在我单击一个按钮后，浏览器会无限期地等待响应。我可以单击其他按钮并仍然进行切换，但它总是在等待响应。如何从该远程设备获取响应并在网页上显示（或对其进行操作），并防止页面无限期等待？这是将此数据字符串发送到远程 IP 的正确方法，还是有更好的方法？这是代码：

1) 使用 PHP 设置 Apache Web 服务器

2) 下载PHP Telnet脚本（或任何其他用于 PHP 的 Telnet 库）

3) 修改字符串

    if ($this->fp=fsockopen($ip,23)) {

至

    if ($this->fp=fsockopen($ip,100)) {

（据我了解，您的设备响应端口 100？）

4）用这样的东西制作PHP脚本（替换username并password使用您的凭据）： proxy.php

<?php
require_once "PHPTelnet.php";
$telnet = new PHPTelnet();
$command = $_GET['command'];
$result = $telnet->Connect('192.168.5.30:100','username','password');
if ($result == 0) {
$telnet->DoCommand($command, $result);
echo $result;
$telnet->Disconnect();
}
?>

5）制作与此类似的HTML页面（这是非常基本的，只是为了给您一些想法并替换yourhost为您的网络服务器的IP）：

<html>
<body>
<form action="http://yourhost/proxy.php" method="GET">
Enter command 
<input type="text" name="command">
<input type="Submit">
</form>

<form action="http://yourhost/proxy.php" method="GET">
<input type="hidden" value="CL1I3O1T" id="Backyard Apple TV" name="command" />
<input type="Submit" value="Apple TV">
</form>

</body>
</html>

复制 HTML 文件的最后一部分以添加其他命令。将实际命令放入输入中value，将hidden标签放入输入value中submit。

I know this post isn't tagged PHP, but I finally got this problem solved with PHP sockets. This web page will respond to a web page button press, open a socket to a remote IP, send a string of data, and finally close the socket. As I mentioned originally, the remote device is an ethernet to serial converter, which is connected to an audio switcher. I can now control this ethernet connected / serial controlled audio switcher using a PHP webpage. The code is pretty simple, but getting the syntax correct was difficult. Thanks to all of those who helped! I hope this helps someone else... Here is the code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<?php

$input=$_POST['input'];
$sock = fsockopen('192.168.5.30:100', NULL, $errno, $errstr);
fwrite($sock, $input);
echo fread($sock, 4096)."\n";
fclose($sock);
?>
