4.1.2.2 Operating System Support

On Windows machines, the CDC will enumerate as Curiosity Virtual COM Port and appear in the Ports section of the Windows Device Manager. The COM port number can also be found there.

Info: On older Windows systems, a USB driver is required for CDC. This driver is included in installations of MPLAB® X IDE.

On Linux machines, the CDC will enumerate and appear as /dev/ttyACM#.

Info: tty* devices belong to the “dialout” group in Linux, so it may be necessary to become a member of that group to have permissions to access the CDC.

On MAC machines, the CDC will enumerate and appear as /dev/tty.usbmodem#. Depending on which terminal program is used, it will appear in the available list of modems as usbmodem#.

Info: For all operating systems: Be sure to use a terminal emulator that supports DTR signaling. See Signaling.
