I send this command "AT+CUSD=1,"*511#",15", the answer is:
'+CUSD: 1,"Points Noudjoum
1: Mes points
2: Convertir en Units
3: Convertir en cadeaux physiques
4: Points Bonus
5: Catalogue
6: Conso
Tapez 1-6",15'
Here I need to send again the integer 1, 2, 3, 4, 5 or 6 depending on the option i want but at this point I can't send another AT command "AT+CUSD=1,"*113#",15" for example, it shows an error because it is expected to send the number of the option.
How can I break or cancel it so I can send another AT command ?
