Webesptool.py resets ESP32 automatically by asserting DTR and RTS control lines of the USB to serial converter chip, i.e., FTDI, CP210x, or CH340x. The DTR and RTS control lines are in turn connected to GPIO0 and EN ( CHIP_PU) pins of ESP32, thus changes in the voltage levels of DTR and RTS will boot the ESP32 into Firmware Download mode.
