Hi @Fabricio-ESP, when you have time please take a look

[Fabricio-ESP]

Using VSCode 1.9 this issue does not happen anymore on Windows, since VSCode will run the commands using the "default" terminal for the operating system, which on windows is PowerShell.

On Linux the Build and Flash commands works without any issue, but the monitor commands is showing unexpected behavior.
The command sent to terminal still uses "export" which is not understood by PowerShell 7. Additionally, it seems that the python path and the monitor command is being sent twice to the terminal application.

Additionally, when re-executing the monitor command, the command is not properly finishing the previous task before sending new commands.

Confirm it is working now with the latest changes. Command is not repeated in shell and it is working well in Windows and Linux.
