the idea that modems were like, really long serial cables (in some contexts) is so weird to think about
no ip, no packets, just bytes
just computers screaming at each other
i kinda yearn for this method of communication, but also understand that it'd be a real pain
and like, it's almost impossible to do these days, with no ip, no packets anywhere in the chain... i'll bet that even with a landline now, it gets turned to voip somewhere in the chain...
