In the example is stated that the function is run between one loop and the next, but actually the call to the function was missing. The comment also state that the response can be delayed using a delay in the loop,so I think that the way it should be is so by only adding a call to the function serialEvent as first operation in the loop. I so added this call.

Serial Event example
|
|
|
|
When new serial data arrives, this sketch adds it to a String.
|
|
When a newline is received, the loop prints the string and
|
|
clears it.
|
|
|
|
A good test for this is to try it with a GPS receiver
|
|
that sends out NMEA 0183 sentences.
