I have those memories too! I'm certainly not claiming to have invented the idea of dial-up. The idea for this library is to provide a soft modem, highly configurable (thanks to liquid DSP), which comes "batteries-included" with a TCP stack (thanks to lwip). The examples shown in the README can even run on a nearly-ultrasonic modem profile whose spectrum content lies >= 19kHz
