Usage:
Change params at the top of the script as needed, then upload to target and begin listening on the inputted port.
TTY functionality:
The script attempts to spawn a tty shell using python; this will fail if python is not installed on the target system. This assumes that either 'python' or 'python3' binaries are runnable by the user that gets logged in.
