Wow! I can’t find the thread but someone had this problem before! (I’ll edit it in once I find it). It comes down to the fact that the serial Port just skips output, randomly, for whatever reason. Our previous fix was to just test whether or not `list` actually contained a second element.

I know you’ve must have spent a lot of time on this, but I actually believe someone’s made a very polished library that does what you want and more (yay?).

But if you’re just using this as a learning exercise, we can still tackle the original problem
