The following commands can be sent from client to server:
* `QUIT` – closes the connection
-* `FIB` followed by positive integers (all tokens separated by ` `; for each
+* `FIB` followed by positive integers (all tokens separated by ` `); for each
such integer n, calculates th nn-th Fibonacci number (this allows for testing
parallel CPU-heavy computation)
+Additionally, the server regularly sends a counter state to the client.
