// Disable SIMULATE_SERIAL_PORTS only if all the following are true:

// 1. You have an Arduino or compatible board attached to your machine and
// properly appearing as the first virtual serial port ("first" is very loosely
// defined as whichever port shows up in serial.getPorts). We've tested only
// the Atmega32u4 Breakout Board and Arduino Leonardo; note that both these
// boards are based on the Atmel ATmega32u4, rather than the more common
// Arduino '328p with either FTDI or '8/16u2 USB interfaces. TODO: test more
// widely.
//
// 2. Your user has permission to read/write the port. For example, this might
// mean that your user is in the "tty" or "uucp" group on Ubuntu flavors of
// Linux, or else that the port's path (e.g., /dev/ttyACM0) has global
// read/write permissions.
//
// 3. You have uploaded a program to the board that does a byte-for-byte echo
// on the virtual serial port at 57600 bps. An example is at
// chrome/test/data/extensions/api_test/serial/api/serial_arduino_test.ino.
