Now, plug your board. In Terminal, type:
ls /dev/tty.*
This will show you the current serial connections, which will now include your board.
A new listing has appeared called /dev/tty.usbmodem141441 . Theī¤ tty.usbmodem1
41441 part of this listing is the name the example board is using. Yours will be called
something similar.
Using Linux, a new listing has appeared called /dev/ttyACM0 . The ttyACM0 part of
this listing is the name the example board is using. Yours will be called something
similar.
Connect with screen
Now that you know the name your board is using, you're ready connect to the serial
console. You're going to use a command called screen . The screen command is
included with MacOS. To connect to the serial console, use Terminal. Type the
following command, replacing board_name with the name you found your board is
using:
screen /dev/tty.board_name 115200
The first part of this establishes using the screen command. The second part tells
screen the name of the board you're trying to use. The third part tells screen what
baud rate to use for the serial connection. The baud rate is the speed in bits per
second that data is sent over the serial connection. In this case, the speed required
by the board is 115200 bits per second.
