Nothing happens
Do you get a new prompt (the > character)?
No
Or what happens if you type 1+2 and hit enter?

What kind of ESP8266 board do you have?
NodeMCU v2 or v3 - I'm not exactly sure which version.
What happens if you press reset on the ESP8266 while the IDE is
connected?The error is the same..
Connected to COM8 (No response from board) -
Hi All! Need help.
Espruino IDE (Native) espruino_ide_win64_0v72.1
Firmware ESP8266 2v08IDE Error:

There is a connection via the COM-terminal, but the IDE does not want to connect! What is the problem?

Here are sequentially screenshots of the IDE when connected to the board.
Maybe the problem is in the IDE settings or in the drivers? I am using windows 8.1.
