ESP32-CAM does not print anything on Serial Monitor

I was given messages that my other posts from other posts Esp32-Cam Serial port problem
-- was moved here by some admin.

There are posts all over about this same problem :
[Serial Monitor Not Working On Esp32(SOLVED)]
[<SOLVED>IDE 2.0.0-rc2 problem with serial monitor and ESP32-CAM]

  • There are mentions of solutions - but nothing actually fixes it - people still repeat posts of not solved.
