This has to do with the speakers picking up signals from your mobile phone. Before a mobile phone rings, if it is close to the speakers, somehow the signal would make the speakers go "dudud dudud dudududu".
Specifically, GSM phones would do this
They all did. GSM was just a little stronger.
Yeah, I definitely remember this from before GSM was a thing
No, my dial up modem in my desktop pc. Some. Pcs use the external speaker, some used the motherboard speaker and my dial up modem had its own speaker. God forbid someone picked up a phone to dial.
The meme is about incoming phone calls and its effects on the speakers. It has nothing to do with the modem.
Dial up modems, like the ones the poster mentioned, could receive incoming phone calls as part of their normal function
The "dudud dudud dudududu" sound in the meme is completely different to the dial-up modem handshake sound "skreeee-chirrup-buzzzzwheee-krkkrkkrk-shhhhh".
The "dudud dudud dudududu" sound happens BEFORE an incoming mobile phone call. The "skreeee-chirrup-buzzzzwheee-krkkrkkrk-shhhhh" sound happens after an incoming land-line call is picked up.
