Dealing with AT command respond terminator(Solved)

Thank you PaulS, :wink:

Here is my latest update of that serialEvent1 thing. It's actually working now, Although I had to totally change my finding end string Procedure.

void serialEvent1(){

  char caractere_entrant;  
  
  while (Serial1.available()) {
    
    longueur_de_ligne++;
    caractere_entrant = (char)Serial1.read(); 
    chaine_entrante += caractere_entrant;
    
    if ((caractere_entrant == '\n')&&(dernier_caractere == '\r')){

      Compte_retour++;
      if (longueur_de_ligne < 3){chaine_complete = true;}   
      longueur_de_reponse += longueur_de_ligne
      longueur_de_ligne = 0;
   
    }

    dernier_caractere=caractere_entrant;
    
  }

}

Now, it's actually looking for a newline that has at most 2 characters, since the AT command has 3 characters minimum, "+OK" in his answer this settle the thing.
