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. Hayes was no exception; the company introduced its v. Their attention turned to Asymmetric Digital Subscriber Line ADSL , which ran over the existing wiring and did not block a telephone connection in the process. Through all these tests the Accura external maintained a rock-solid connection. At the time, Hayes was one of the few modem companies with the capital and engineering wherewithal to develop entirely new modem architectures.

If need be the user can set the default to either K56Flex or V. This review concerns only 56l external model for reasons that will become apparent. The first of these, v. This smart modem approach dramatically simplified and automated operation. When this was received from the computer, the modem would switch from data to command mode.

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. One option would be to signal this change—”put yourself into command mode”—via one of the many pins in the RS cable.

By the mids their modems were also based on the Rockwell chip set, and had little to distinguish themselves from other vendors. Both of these items’ sales were apparently dismal.

The company is well known for the Smartmodemwhich introduced a control language for operating the functions of the modem via the serial interface, in contrast to manual operation with front-panel switches.

An effort was started to move into the market for ADSL and cable modemsbut this was a multi-year effort during a period when USR increasingly took over the market. I am still awaiting a solution from Hayes and will report on the internal Accura when it is up and running.

We, the Manufacturer or our representatives may use your personal information to contact you to offer support for your nayes activity and for other related purposes. 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.

The name referred to the way the modems could “ping-pong” the single high-speed link between the two ends on demand, in a fashion similar to the USR and Telebit protocols. The mdoem and 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.

The modem market in the s was very simple and stagnant. Also differentiating Hayes from its competition was the Smartmodem’s use of the guard time. Business picked up quickly, and in January they quit their jobs at National Data to form their own company, 556k. Thank you for your feedback.

The same results were encountered so I switched to a Dell Optiplex system for another kick at the can. As the modem market expanded, competitors quickly copied the Hayes command set and often the Hayes industrial design as well. 56,

Hayes was never able to respond effectively. They remained a major vendor throughout the s, periodically introducing models with higher throughput.

Hayes Accura V/K56Flex Internal and External Data/Fax Modems

There were optional systems to dial the phone or pick it up, but these were generally implemented as separate devices also intended to be used on one end of the connection or the other.


The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. In an attempt at diversification in January it modwm acquired most of the assets of local area network software developer Waterloo Microsystems Inc mmodem 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 eventually purchased two of their competitors, Practical Peripherals and Cardinal, turning them into low-cost brands in order to compete with companies such as Zoom Telephonics. When they mode, to the Smartmodemthey simply extended the set further, using the hwyes syntax.

The Accura 56K loaded web pages much more crisply than the average In order to filter out these “accidental” sequences, Heatherington’s design only switched to command mode if the sequence was led and followed by modwm one-second pause, the guard timein which no other data were sent.

In the other, command modedata mdem from the computer were instead interpreted as commands. Another confuses the original Smartmodem with the later V-Series modems, reversing the introduction dates and features. 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.
