Hayes S100 modem (80-103A) commands

Sorry - I wasn't paying too much attention to this thread, but I have the manual for the Hayes S100 modem (80-103A) which includes a short modem control program written in 1977 by Dale Heatherington (the co-founder of DC Hayes; guess who was the marketing guy and who was the engineer!). Control was by bit-setting a couple of control bytes to handle bit (baud) rate (high/low - typically 300/110 bps, but low rate could also be set to 75 or 134.5 bps). Other bits set transmit enable (on/off), mode select (answer/originate), break, self-test, ring indicator, and off hook. The manual includes a chapter on "Applications". Section 5.5 Telecommuting is reproduced here: "The energy situation being what it is, more and more people are seriously considering alternatives to commuting. If your job consists mostly of slaving over a hot computer terminal, the 80-103A may offer an economical way for your job to come to you instead of the other way around. Of course you would want to make an occasional trip to the office for meetings, but think how much pain and energy you could save. You might even be able to move to that beautiful valley 'way up there in the mountains..." Of course the hot setup was the PMMI modem which could be overclocked to 450 baud, but Don Brown died in the late '70s (?) and the company disappeared. But what the world was really waiting for was a good 1200 baud modem... Jack Rubin USRobotics 1984-95
