Really Geeky Modem Technology Patented

Hayes Smartmodem 300June 7, 1983

Michael Eaton is granted a patent for the AT Command Set for Modems, which had created a standard language for interacting with modems. Two years earlier, the rights for this command set were purchased by the Hayes Corporation and incorporated into the Hayes Smartmodem 300 as the “Hayes Command Set.” The protocol will become an industry standard used for years to come.

In the early 90’s, needing to use modems so that I could connect to pre-Internet bulletin board systems, I learned the AT command set. I then used and supported modems extensively for about 15 years, and occasionally still do. Because I worked with modems so much, I used to be able to speak the AT command set in my sleep. I know, it impresses the ladies.
