Kid told me that he just watched “some crazy old movie” about how a kid hacked into NORAD.
You young whipper snappers and your fancy DOS terminals…10,000 years ago I sat at a teletype terminal and tried to learn to program in BASIC. Oregon Trail and Missile Attack are a whole 'nother experience when done by printed media only.
I can still hear the sound of the teletype clacking…
I was taught Lotus 1-2-3 on MS-DOS in college. Do with that information what you will.
Terminals I played with had no screen just a dot matrix printer. My God, the sound…
I only used one of those once, it was atrocious. People must have shed tears of joys when screens took over.
PFY: “Hey, computers used to be all text just like that with no graphics, did ya know?”
BOFH: “No shit” uninstalls X/Wayland from PFY’s computer remotely
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.
Would it make you feel better that literally today I had to troubleshoot a RS-232 at work?
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.
Comparing RS232 to cancer is a good analogy.
I hate it but as you said it has its niche and there really aren’t better options for what it does. If someone else has a means to wire up +100 sensors to one system that doesn’t involve enough wiring to encircle an entire city or an unbelievable reliable means to do M2M between two machines that’s secure simply because everyone who knows how to tap it has a high paying job I am all ears.
Technically, if it’s a land line port and still connected to an exchange that hasn’t gone completely VoIP (that’s a thing where I am), it might actually be possible to build a charger module that plugs into that port.
Would it be worth it, though? … No.
Low power is supplied over old land-lines for the purposes of making telephones ring and powering other handset bits and pieces, within reason of course. Using it for anything else is undoubtedly illegal as phone lines aren’t rated for huge power draws.
(If you’re interested, there are videos online where people have hooked up LED lamps etc.)
But, let’s say that module existed and was legal. Your niece still wouldn’t be happy with it.
To avoid burning out to the telephone line, any such device would have to be a r e a l l y s l o w trickle charge.
I wouldn’t even think about it for emergency power outages. A battery backup is a better option.
There’s even an instructables on how to do it.
