Reading a numerical string from serial monitor to perform an action?

You might want to look at Serial.ReadBytesUntil().

And then atoi().

Here is my loop code at the moment:

void loop() {

  Serial.print("Send an integer value between 1300 and 1700 ");
  Serial.println("microseconds to test speed...");
  
  while (Serial.available() == 0);
  pulseWidthInput[0] = Serial.readBytesUntil(not sure what to put here);
  Serial.println(pulseWidthInput);
  
  int pulseWidth = atoi(pulseWidthInput);
  
  if (pulseWidth >= 1300 && pulseWidth <= 1700) {
  
    Serial.print("Testing speed at: ");
    Serial.println(pulseWidth);
  
    leftServo.writeMicroseconds(pulseWidth);
    rightServo.writeMicroseconds(pulseWidth);
    delay(6000);
    leftServo.writeMicroseconds(1500);
    rightServo.writeMicroseconds(1500);
    
  }

The Arduino reference article isn't too specific and doesn't include an example of Serial.readBytesUntil(). How exactly should I go about with the parameters of this function?
