[cctalk] Re: RS232 then and now

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.
