# If set to 1, auto-detection of TTYs will also allow clones. This has a slight
# disadvantage for users of genuine Arduino Mega 2560: If the board is not
# plugged in, it will fall back to a detection that may yield false positives.
# However, most people will plug in their boards correctly prior to typing
# `make term`, so this is only a small loss for users of genuine
# Arduino Mega 2560 but a big win for users of cheap clones. Still, users that
# only will ever use genuine Arduino Mega 2560 boards can disable this via their
# .profile or .bashrc if they want.
