In order to filter out these “accidental” sequences, Heatherington’s design only switched to command mode if the sequence was led and followed by a one-second pause, the guard time , in which no other data were sent.

This was not simple unless the modem “knew” what data were initially being sent, allowing it to time the bits and thereby guess the speed.

By the early s, this was a major focus of the company.

A few external modems already offered the ability to dial the phone by entering a phone number when the modem was first started, but the real problem was somehow sending a command to hang up, while the modem was already connected.

Hayes’s slow entry into the high-speed market led to a fracturing of the command set. This could be addressed in internal hayez that plugged directly into the computer’s motherboard. Calculate Varies based on location and shipping method.

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.


Hayes realized that changes in the telephone networks would hates render the modem, in its current form, obsolete. 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.

Minimum monthly payments are required. Hayes’ job was to set up modem connections for NDC’s customers. At the time, modems generally came in two versions, one for the end-user that required the user to dial the phone manually and use an acoustic coupler for connection, and another dedicated to answering incoming calls that was intended for use on the minicomputer or mainframe the user was calling into. Rockwell had taken their commands from the V-series Smartmodems, so by the mids the market was once again based largely on a “real” Hayes command set.

Modem companies quickly incorporated v.


No additional import charges at delivery! 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. 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.

In one, data modeall data forwarded from the computer were modulated and sent over the connected telephone line as it was with any other modem.

Today almost all modems use a variant of the Hayes command set. They then split their line into the Accura and Optima brands, offering the Accura as a low-cost model, although the feature sets were not that different between the two lines.

Hayes started producing similar products at a “hobby level” in his kitchen in April with his friend and co-worker, Dale Heatherington. When they moved to the Smartmodemthey simply extended the set further, using the same syntax. Some popular computers, like the Ataridid not even integrate internal slots.
