> The connection shows up as a ethernet port

OK but what then? I've had ethernet ports on my computers since I can remember, and that hasn't magically allowed me to transfer data back and forth just by plugging a patch cable into both machines. What software is at work here?

I’m guessing if they’re using Windows it’s boring old SMB?

Depending on what you want to do on what O/S, batteries may or may not be included. I use Moonlight on a Mac to control a Windows 10 PC running Sunshine--lower latency than Remote Desktop (which I don't have anyway in the Home edition), and nicer looking than Parsec.

When you connect a patch cable directly (no crossover cable needed in the 21st century), you'll likely find that each system has a self-assigned IP in the 169.254 network.

A friend has reminded me that with Linux, it can be as basic as piping tar between the two machines using nc. (There's probably a friendly frontend to this somewhere that will allow the machines to mount each other's filesystems with fuse, though...)
