I'm running a fresh today installation of Ubuntu 16.04 for 64 bit machines at home. Yesterday I was working on somebody else's Windows 10 machine and once I figured out baud rates had no issues communicating with my Arduino Uno and three NodeMCU ESP8266's.
This is day two with my Arduino's. I'm excited about the project I am working on, but I can't get past the serial monitor.
Scripts upload and work, but the serial monitor offers either nothing or

Nothing remotely intelligible.
Four devices that all communicated yesterday on a different machine.
I can change colors on a programmable LED strip, but nothing out of the serial monitor. Obsessively tried every baud rate on every device for longer than I should have.
I'm stumped. Any nudges in the right direction would be appreciated.
