@puniko I only know about the "Airgapped Transfer Protocol" because #UUCP is old amd ancient and not really good at all and doesn't work or gets implemented on modern hardware...

Whereas #ATP aims at transfering files using only cameras and screens...

It won't replace like a #USB or #Ethernet cable but can replace a #serial console...
