Note
You may need to adjust the serial device path (/dev/ttyUSB0) based on your system and the type of cable you use. You can find the correct path by running dmesg | grep -i tty after connecting the serial cable to your PC and router/switch.
- Save configuration and exit.
Warning
minicom uses <key> shortcuts for navigation. Make sure they don't conflict with some of your other terminal shortcuts. E.g. my tmux configuration uses C-a as prefix key, and that conflicts with minicom, so I usually have to use minicom outside of tmux.
