If cable is not plugged in this happens:

<class 'Exception'> The serial is not working. Please make sure the lights are plugged in and that you don't have any other dmx scripts running and make sure the port is correct <traceback object at 0x0D152968> Traceback (most recent call last): File "C:\Users\Joshu\OneDrive\Documents\python new comp\dmxTest\PiDMX\PiDMX\pydmx.py", line 59, in init self.ser = serial.Serial(port,baudrate) File "C:\Users\Joshu\AppData\Local\Programs\Python\Python38-32\lib\site-packages\serial\serialwin32.py", line 31, in init super(Serial, self).init(*args, **kwargs) File "C:\Users\Joshu\AppData\Local\Programs\Python\Python38-32\lib\site-packages\serial\serialutil.py", line 240, in init self.open() File "C:\Users\Joshu\AppData\Local\Programs\Python\Python38-32\lib\site-packages\serial\serialwin32.py", line 62, in open raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError())) serial.serialutil.SerialException: could not open port 'COM3': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2)

During handling of the above exception, another exception occurred:

Now deals with the error when it is pulled and then checks to see if works until plugged in again so then works when plugged in again
