What potential pitfalls should be considered when using the PHP Serial Extension for communication with hardware devices?

One potential pitfall when using the PHP Serial Extension for communication with hardware devices is the lack of error handling, which can lead to unexpected behavior or crashes. To mitigate this risk, it is important to implement proper error handling mechanisms in your code, such as checking for errors after each serial communication operation and handling them appropriately. 

// Open serial port
$serial = new PhpSerial;
$serial->deviceSet('COM1');
$serial->confBaudRate(9600);
$serial->deviceOpen() or die("Unable to open serial port!");

// Send data
$written = $serial->sendMessage("Hello, Arduino!");

// Check for errors
if($written === false) {
    die("Error sending data!");
}

// Close serial port
$serial->deviceClose();
