 - `no_crlf` - just send a line feed (`\n`) for user input rather than carriage return + line feed (`\r\n`)
 - `escape` - change what character is used as an escape sequence for commands (e.g. if set to `escape=a`, Bytenuts can be exited with `ctrl+a, q`)
 - `inter_cmd_to` - Set a timeout in milliseconds that must be met. Useful for pasting in multiple lines and ensuring a short delay in between the commands.
