Sorry, but I don't understand the question. Can you post some code that shows what you are doing ? Apart from variable names code can overcome the language barrier.

You mean something like this?

char msg[] = "Arduino";

void readMsg(){
  byte i = 0;
  //lets read byte for byte but leave room for NULL
  while(Serial.available() && i < (sizeof(msg) - 1)){
    msg[i] = Serial.read();
    i++  ;
  }
  msg[i] = '\0'; //end with NULL
}
4 
      msg[i] = '\n'; //end with NULL

\n is NOT the NULL terminator. \0 is.

You're right! Quick write error, oops...

@mochbilal, have a look at the examples in Serial Input Basics. They are simple and reliable and read the data into a char array.
