💡Hayes Command Set Pioneers Modem Automation in 1981
How a 40-year-old command set still runs the world
TL;DR
The Hayes command set, developed in 1981, revolutionized modem automation. It's still the backbone of dial-up modems today, despite newer standards. Essential for anyone working with legacy systems.
In 1981, Dale Heatherington and Dennis Hayes introduced the Hayes command set for the Hayes Smartmodem, automating modem operations. This set became the industry standard, powering dial-up connections and influencing modem commands for decades. Developers working with legacy systems or dial-up connections should pay attention, as the Hayes command set remains crucial for compatibility and automation. The original set covered 300 bit/s modems, expanding to 2400 baud with new commands. By the early 1990s, the TIA/EIA-602 standard formalized the 2400-baud command set, but variations persist. The Hayes command set's influence is a testament to its enduring relevance in the tech industry.
Key Points
