@dandavis Thank you for that clarification - That was pretty much what I was asking, but couldn't figure out how to ask (terribly sorry).I suppose it would have been best to phrase the question as 'How does Serial.available() go from true to false?

| Feb 6, 2018 at 3:53 | comment | added | dandavis | yes, you read() until available() is false, at which point the buffer is considered empty. | |
| Feb 6, 2018 at 3:23 | comment | added | jsotola | the only way you can "remove" a byte, is to overwrite it. ... i do not think that the library code does that, because that would be a waste of resources. ... i'm sure that the pointer into the buffer is the only thing that has changed. | |
