What Dial Switch do in ESP8266-DEVKITC

[ktauchathuranga]

guys,
I have ESP8266-DEVKITC dev board, and it has a dial switch. When I reached in documents, it said its for " Auto Download and Flow Control"
I don't know what that means, can someone please explain that to me?

I'd also like to know where to find the details about these two options. The datasheet does not explain much.

Educated guess: Auto download will enable RTS and DTR to reset and put the chip into download mode using software, similar to what all ESP32 boards do by default. Flow control will connect RTS and DTR from the USB-serial chip to the corresponding pins on the ESP8266 so you can do hardware handshaking for flow control.

are there any guides on how to do it? or any videos?

On how to do what? Flip the switches? You generally take off the brown kapton tape (that's there to allow the pick&place machine to put the thing on the PCB in the factory), then you reach in with a pen or tweezers or something to flip them.
