What actually were those noises that dial-up modems made when connecting? What caused the noise?
In: 15
The noise is deliberate. It’s so you, the human, can hear the 2 systems negotiating their connection. If the connection failed, you would know through listening to it what the cause of the failure might be.
For example, if my modem called your modem, but your dad answered the call instead then I would actually be able to hear him through my modems speaker. Mine would make the modem sounds, then I’d hear your dad’s garbled voice swearing.
Same if your modem never answered the call. People who were really good at listening to the modem sounds could actually tell if there was a compatibility issue or if the modems were unable to match speeds.
