On a Windows computer, you can see the virtual serial port by going to your computer’s Device Manager and expanding the “Ports (COM & LPT)” list. You should see a COM port labeled “Pololu A-Star 32U4”. In parentheses after the name, you will see the name of the port (e.g. “COM3” or “COM4”). Windows will assign a different COM port number to the device depending on what USB port you plug it into and whether it is in bootloader mode or not. If you need to change the COM port number assigned to the A-Star, you can do so using the Device Manager. Double-click on the COM port to open its properties dialog, and click the “Advanced…” button in the “Port Settings” tab. From this dialog you can change the COM port assigned to the device.

On a Windows computer, you can see the rest of the USB interface by going to the Device Manager, selecting View > Devices by connection, and then expanding entries until you find the “Pololu A-Star 32U4” COM port. Near it, you should see the parent composite device.

On a Linux computer, you can see details about the USB interface by running {{fname|lsusb -v -d 1ffb:}} in a Terminal. The virtual serial port can be found by running ls /dev/ttyACM* in a Terminal.
On a Mac OS X computer, the virtual serial port can be found by running {{fname|ls /dev/tty.usbmodem*}} in a Terminal.
You can send and receive bytes from the virtual serial port using any terminal program that supports serial ports. Some examples are:
* the Serial Monitor in Arduino IDE,
* the [https://www.pololu.com/docs/0J23 Pololu Serial Transmitter Utility],
* [http://sites.google.com/site/terminalbpp/ Br@y Terminal],
* [http://www.chiark.greenend.org.uk/~sgtatham/putty/ PuTTY],
* [http://ttssh2.sourceforge.jp/ TeraTerm],
* [http://www.columbia.edu/kermit/ck80.html Kermit],
* [http://www.gnu.org/software/screen/ GNU Screen].
Many computer programming environments also support sending and receiving bytes from a serial port.
