kar*_*nan 5 html javascript php mysql
我正在使用phpSerial在 COM 端口 (COM10) 上进行通信。
这是我的代码：（与示例代码非常相似）
<?php
require('php_serial.class.php');
echo "<html>
<head><title>Test MySQL</title></head>
<body>";
// Let's start the class
$serial = new phpSerial;
$serial->deviceSet("COM10");
$serial->confBaudRate(1200);
$serial->confParity("none");
$serial->confCharacterLength(7);
$serial->confStopBits(1);
$serial->deviceOpen();
$serial->sendMessage("Hello !");
$read = $serial->readPort();
echo "here it is";
echo $read;
echo "here it was";
sleep(1);
$serial->deviceClose();
?>
</body></html>
这是我得到它运行的响应：

here it ishere it was
知道为什么这不起作用吗？
我的设备已连接到 COM10，并显示为Silicon Labs CP210x USB 转 UART 桥接器 (COM10)
