Arduino ZERO (SAMD21) SERIAL1 Buffer size

Not sure about that @bembu_account.

But @westfw, if I try to make the changes (Add the commits that Arduino made to my Adafruit files) I end up running into issues with other methods not existing/being defined. Is there anyway I can fix this rather than being a sitting duck and waiting for Adafruit's developers to get around to it?

Thanks again.
