so,  
atoi of that string might be not the right idea.  
and yes, that might be the most efficient protocol for this  
but can never be used via a terminal ( they all ascii )  
and actually i prefer the complete opposite way to do communication:

( your way also needs that value decoding… ) but there are many other way, the fastest still would be a byte stream ( not ASCII ) but i hate, as i can not read it in Arduino IDE terminal t…
