I found that os detection does not work for Mac OS.

Please use:

import platform

if platform.system() == "Linux":
    import fcntl

def sender(self):
    while True:
        if not(self.enabled):
            continue
        if platform.system() == "Linux":
            fcntl.ioctl(self.desc, 0x5427) # Yeah, it's magic. Start Break (TIOCSBRK)
            time.sleep(0.0001)
            fcntl.ioctl(self.desc, 0x5428) # Yeah, it's magic. End Break (TIOCCBRK)
        else:
            self.ser.send_break(0.0001)

I tried to use a pull request, but it was to cumbersome.

Thanks for the code, it works for me, but with changes merged to master for OS detection, it easier to use.
I am a mac and linux user :)

I got one of those cheap modules, and tried to connect it to a raspberry pi 3b. I see the light on the board flashing, but the dmx light isnt responding. The light just blinks with the display, as if there isnt any valid dmx signal coming in.

To check if the dmx module worked, I tried the kmtronic.com DMX Tester on Windows 10, and it worked fine.

Heading back to the raspberry pi, and I again can't get it to work. Using the test.py file to test.
