I'm not clear how this works. Because if I change the baud rate it
definitely stops any communication between the laptop and the Arduino so
baud rate must have some meaning in this case. I also tried using a python
program I wrote and got the same behaviour of working up to 19200 then
stopping so I don't think it's an issue with Pure Data. Maybe a cable issue?
