SerialEvent occurs whenever a new byte comes in the
hardware serial RX. Don't do complex things here, as the
processor halts the regular program to run this routine:
SerialEvent occurs whenever a new data comes in the
hardware serial RX. This routine is run between each
time loop() runs, so using delay inside loop can delay
response. Multiple bytes of data may be available.
