Steve, remember that digital electronics ( I.E. integrated circuits like uarts) weren’t
around during the early days of data transmission. It was all analog back then, coils,
capacitors, and resistors, so then ideas regarding fast transmission had to wait for the
technology to evolve. Then as ic’s became available, what you could do with them sparked
new ideas. Example: data compression within the modem using a microprocessor, thus getting
higher overall throughput than the theoretical maximum of just the modulation rate.
True, though "digital electronics" and "integrated circuits" are not
directly related. Digital circuits were first built with relays and with tubes. What
makes them "digital" is that they deal in ones and zeroes rather than with
continuous real-valued signals.
