Use the console port on Linux (Debian)

Sometimes you need to use the serial port for debugging or analyzing the behavior on a USG/ATP/NXC/NSG. On Windows, this is very simple by using Tera Term or Putty. On Linux, it is even more simple, if you know how to do it.

1. Plugin the USB to serial cable to your PC/Laptop and to the target device 
2. Open a terminal
3. Type in 
   

   sudo screen /dev/ttyUSB0 115200,cs8,-ixon,-ixoff,istrip

4. Enter the password for the current user (Must be a sudo-allowed-user)
5. Hit enter again, you should now see the login for the USG

Done, the terminal is now connected to the USG

To quit the session you just hit Ctrl-a and k, type y and hit enter

• Ctrl-a + k: This option is used to kill the screen session.
• you need to confirm the kill by typing y (yes) and press the enter key
