Help with converting a sting of chars to an int via toInt().

Something bothered me about my answer. Use this instead:

const int BUFFSIZE = 6;


void loop() {		
   int bytesRead;

   if (Serial.available() > 0){
      bytesRead = Serial.readBytesUntil('\n', incomingStr, BUFFSIZE );
      ShowMeWhatArrived();
    // more of your code...
}  // End of loop()

void ShowMeWhatArrived(int bytesRead)
{
   incomingStr[bytesRead] = '\0';           // Make sure we can treat it as a string

   Serial.print("Direction: ");
   Serial.print(incomingStr[0]);
   Serial.print("Left-Right: ");
   Serial.print(incomingStr[1]);
   Serial.print("Magnitude: ");
   Serial.print(atoi(&incomingStr[2]));
}

There...more better! Now if a one or two digit value comes in, the null is placed in the correct position.
