Linux OS family treat the tty (terminal) as any other file, so it has an actual file path we can write into.
When a client runs a bit command (using the env variable of enabling the cli-server) it sends its tty path to the server. The server (in the cli-raw route) monkey patches (no choice here) the
process.stdout.writeand adds additional write - to the tty path. This way, the client gets all the data stream in between the request and the response.
