The serial port that's connected to the ESP chip. This can be overridden by setting the ESPPORT
environment variable.
This value is ignored when using the CMake-based build system or idf.py.

The flasher tool can send data compressed using zlib, letting the ROM on the ESP chip
decompress it on the fly before flashing it. For most payloads, this should result in a
speed increase.
