Serial port do not work with another program

[luizabbadia]

Hi! I used esp32 cam in my project for detection and work well when using arduino interface and serial port.
When I try to use any program that reads serial port I see nothing, it does not work! I can’t see the serial output!! Any hint? Please!

Hi @luizabbadia,

If I recall, this has to do with DTR/RTS settings in your serial program. Try toggling those in different configurations to see if it works. These discussions might also help:
