Accessing CDC
Accessing CDC on Linux
On Linux no drivers are needed, the device should show up as /dev/ttyACM0 or similar. "sudo screen /dev/ttyACM0 115200" can be used to access the device.
Accessing CDC on Windows
On Windows 8.1 and below the "usbser" driver is not automatically assigned to the CDC-ACM device. To install the "usbser" driver see \Windows\USB\CDC . The device can be accessed via COM port emulation programs e.g. PuTTY.
Accessing CDC on macOS
On macOS no drivers are needed, the device should show up as /dev/tty.usbmodem13245678 or similar. The "screen" terminal program can be used to access the device.
