Could work in theory. Back then there it had sonething like 40 volts going through the line and you needed some decent power to make the bell in the phone ring.
But I don’t know if that’s still in use these days.
RS232 is functionally immortal. Its market share in the niches it fills has never – and I’d argue will never – go away, or even shrink all that much. It’s like those lobsters that don’t age at all but if we splice the genes that do that into humans it gives us cancer.
My 10 year old niece asked me what my RJ45 wall socket was while I was fixing her mom’s computer.
“It’s for old telephones”
She then asked me if I had an adapter for it so she could charge her phone.
I almost died.
Rj11/12 are for telephones, rj45 is for ethernet
VoIP phone
Oops, yes. Thats what I meant. STILL died.
Some mad lads actually did this:
Won’t work anymore. Our phone line is completely replaced with fiber. On the other hand i can’t remember any unwarned outages in the last 20 years.
Those old POTS phone lines did carry a few volts.

Would it make you feel better that literally today I had to troubleshoot a RS-232 at work?
