One option would be to signal this change—”put yourself into command mode”—via one of the many pins in the RS cable. Their system was introduced commercially in the SupraFAXModem , which went on to become a runaway bestseller. The end-user was offered much higher speeds while still being able to use existing phones, with the added “benefit” of helping tie the user to the telephone company’s own ISP. The modem would normally start up in command mode. This “history” is confusing the Smartmodem with the original Smartmodem. By using this site, you agree to the Terms of Use and Privacy Policy.

Hayes left the Georgia Institute of Technology in the mids to work at an early data communications company, National Data Corp, a company that handled electronic money transfers and credit card authorizations. Sirkis acquiesced, and a working prototype was soon complete.

Oddly it was the Rockwell chip set that also re-standardized the various command sets back on the original high-speed ones introduced by Hayes.

Business picked up quickly, and in January they quit their jobs at National Data to form their own company, D. Any international shipping is paid in part to Pitney Bowes Inc. For instance, the autodialler was a system that automated the action of picking up the phone and dialing a number, and was normally implemented as a separate box that connected to another port on the host computer.


In an attempt at diversification in January it had acquired most of the assets of local area network software developer Waterloo Microsystems Inc of Waterloo, Ontario and belatedly entered the operating system OS market in June with LANstep, a network OS for small offices, but this was subsequently abandoned in in the face of stiff competition particularly from Novell NetWare.

After dialing their local Internet potima providerthe user could “call out” at high speed to services around the world, so the need for long-distance data calls was generally eliminated.

When this was received from the computer, the modem would switch from data to command mode. The connection hayess disconnection was entirely manual, with the user picking up the phone’s handset, dialing manually, and then pressing the handset into the coupler if a carrier frequency was heard.

In the early s a number of greatly cost-reduced high-performance modems were released by competitors, notably the SupraFAXModemwhich eroded price points in the market. An obvious solution was to use the RS serial port; modems were serial devices and generally driven off RS anyway, ahyes most computer designs included an RS port, or some variant. Although powerful, the internal modem was commercially impractical.

At that price point, Hayes could build a “Cadillac of modems”, using high-quality components, an extruded aluminum case, and an acrylic front panel with a number of LED indicators. No additional import charges at delivery!


Such modems had access to the computer’s main memory, and by dedicating certain memory locations or registers to various status readouts or commands, software programs running on the computer could control the modem.

A number of manufacturers banded together and introduced the Time Independent Escape Sequenceor TIES, but it was not as robust as Heatherington’s system and never became very successful.

While it would have been possible to use some of these pins for the sort of command-switching they needed the “ready” indications, for example, would have sufficed Heatherington instead came up with the idea of using a rarely seen sequence of characters for this duty.

In the end, only two non-modem devices were added to the line. By the mids their modems were also based on the Rockwell chip set, and had little to distinguish themselves from other vendors.
