I am looking for some kind of ready-made (almost ready-made) for the ESP8266 so that using a VCOM or similar program I can see the UART of the ESP8266. One use will be to be able to upload a new program to an ArduinoMega that is far from the computer (different room). It also needs a similar solution for Linux (RPi 3B+).
Can you recommend any proven solution?
