3) if is typed 1, 3: The current alarm will be shown in the second terminal
4) if is typed 2, 1, HH, MM, SS : The clock time will be updated and shown in the second terminal
5) if is typed 2, 2, DD, MM, YY : The clock date will be updated and shown in the second terminal
6) if is typed 2, 3, HH, MM, SS: The clock alarm will be updated and displayed on the second terminalterminal
