For upload firmware need to install ch341 driver ( https://www.wemos.cc/en/latest/w600/index.html)
You can use this terminal for write(comunicate) with w600-pico https://bipes.net.br/aroca/web-serial-terminal/ or use this another terminal https://ttssh2.osdn.jp/ terminal for receive or send data to/from w600-pico or this another terminal https://www.settorezero.com/wordpress/software/zeroterm/
The terminal is not necessary ... only for see errors when run main.py file. I make this tutorial https://github.com/costycnc/w600-pico-micropython-official/tree/main/w600-pico%20upload%20file%20over%20ftp%20windows for first contact with w600-pico
