How to configure and use ESP32-CAM with Arduino IDE and Linux, Initially it disables all the global interrupts and sets the communication interface configurations such as the PWM clock, selection of interrupt pins, presclaer selection, adding parity and stop bits.

If COM4 is already open by another application (such as Arduino's Serial Monitor), then the software cannot access it.
