Operation
A code corresponds to each dosing key. When a serving is requested from a certain key, the dosing device sends the relative code by means
of its serial line. If it receives in reply the same code or a code from 1 to 15 (decimal) the serving is delivered, otherwise it is deleted. The
codes are typical of the traditional interface with the Gicar Stroke Count, which transmits a code that makes it possible to recognize the
staff that is using the machine (1...13 : waiters, 14 : manager, 15 : owner).

The system replies code 15 (decimal), thus enabling delivery of the serving (even if the activation key is inserted).
During any data reading or deletion operation, the system does not reply or replies with a code which is not recognized by the dosing. In this
case, delivery is not performed and the serving is not counted.
