What happened?

I was testing with a config that had a safety door pin defined, with nothing attached to it. The state was seen as active at startup, with no way to make it inactive.

The system spewed continuous [MSG:INFO: Check door] messages and never accepted serial input. That made it impossible to upload a new config file to fix the safety door problem. To get control of the system I had to use esptool to replace either the firmware or the filesystem.
