Server Shutdown

The server shutdown message's only purpose is to remotely disconnect and shut down the server. It uses the fixed format:

!s-sOFF-e!

If successful, the server replies with an ACK control query. If it fails, mostly due to invalid format or a similar issue, it will return with a NACK: _NACK_InvalidQuery (uint8_t c=255). As such, the communication schema for this query will look like the one illustrated on the following diagram.
