Using a Laptop as an HDMI Monitor for an SBC

I'm thinking a better solution for console would be an SSH to serial bridge using just a spare ESP32 and something like ESP32SerialSSHProxy[0]. Haven't tried myself yet, and there is suspiciously few stars on that repo, but that would be a nice lights out-ish management system for some hidden away home automation server.

You can also throw together a cheap software KVM switch[0] using an ESP32 or similar.

That works sometimes. It can be flaky.

Yeah but do you really want to give everyone on your LAN unauthenticated access to the server console? :)

Does serial work for BIOS/UEFI access too?
