====== Serial Console Server ======
The following is from u/jimoxf [[https://www.reddit.com/r/paloaltonetworks/comments/gz5tp7/using_a_raspberry_pi_or_any_linux_pc_as_a_serial/|post on Reddit]].
The 'screen' command can be used to turn any Linux Box (e.g. Pi) into a Serial Console Server.
<code>sudo apt get install screen</code>
Run the following to find the serial devices available
<code>ls /dev/tty*</code>
Plugging in via USB Micro B, a Palo Alto Networks firewall showed up as ''ttyACM0''
Running the following will) will get you to the console prompt
<code>screen /dev/ttyACM0</code>

I'm thinking how this could be combined with a celular modem in the Pi + a Secure Configuration + some remote management tool and this could easily be a handy 'out of band management' box a whole lot cheaper than other alternatives.
