我正在使用phpSerial在COM端口（COM10）上进行通信。
这是我的代码:(非常类似于example code）
<?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>
这是我得到它的响应：

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