To use these extra serial ports to communicate with your personal computer, you will need an additional USB-to-serial adaptor, as they are not connected to the Mega’s USB-to-serial adaptor.. Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several.. On the Mac, the serial port should be something like /dev/tty usbmodem621 (for the Uno or Mega 2560) or /dev/tty.
