I tried changed the “dev” in the call to Serial() - with various parameters.
Put 5 or 6 hours into reading the docs.
I can’t get past getting this simple code to run.
Please Help!!!

(To be fair, there is code there for better errors, which isn’t being executed - I’ll fix that once we find out the issue here.)
