- Sat Aug 20, 2016 1:39 pm #53417 The language reference says:

serial.available()

Will return 0 if no characters in buffer. Will return 1 if serial characters exist in buffer.

serial.available()

This is incorrect. If serial characters exist, the function returns the number of characters in the buffer.
