13. A Demo of g_serial
● Add dtoverlay=dwc2 to /boot/config.txt
● Add dwc to /etc/modules
● Add g_serial to /etc/modules or load with modprobe
● Program can now access data from Virtual Serial from
/dev/ttyGS0
● Imaging: $5 POWERFUL Arduino
● Enable console on ttyGS0
sudo systemctl enable getty@ttyGS0.service
