For Arduino, is there a meaningful difference between carriage returns? Serial.write(0x0d); // hex

Serial.write(13);   // ASCII

Serial.write('\r');  // char

Is one more efficient? I read how it depends on the terminal program. So does that mean the IDE? (This is my first time working with serial comm.)
Is one more efficient?


after compilation it is same for all notations. the function and the value are the same for all 3 notations.
