The SupraFAXModem 14400 is a

, and its introduction drove modem prices sharply downward. Whereas a 9600 bit/s modem was perhaps $599 before its introduction, by the end of the year, $250 14400 bit/s modems were not uncommon.

Background

Supra had been a small player in the computer market through the mid-to-late 1980s, known originally for their external

.

Design

Not content with simply being the first consumer v.32bis modem on the market, Supra made a number of improvements over existing designs. One was the use of a much smaller case, about half the size of most models. The size and shape of modems had initially been set by the original Hayes Smartmodem in 1981, and its case design was widely used a decade later in spite of the internals having shrunk in size considerably over the years. The Supra's smaller design made it much easier to fit on a desk. Additionally, Supra replaced many indicator lights with a two-digit green dot matrix LED display that showed the speed of connection and other information such as "RI" for ring indication and "CD" for carrier detect. Later models such as the LC ("Low Cost") used individual lamps that were a common feature of external modems.

Software

In addition to the basic modem, Supra also introduced software to make better use of all the features of the modem. In particular, Supra re-packaged FAXstf as FAXCilitate, a

routing and similar features.

Problems

The SupraFAXModem was by no means a perfect product. Continued high-speed use caused the driver chipset to heat up, and as the case lacked any airflow, the modems would eventually get hot enough to lose the ability to connect and start dropping calls. Another minor issue was that the status display codes in the alphanumeric display rotated through several different indications, and important information like CD would only be displayed every few seconds. Both of these issues make them unsuitable for "host side" use on a bulletin board system or Internet service provider, but on the client end these issues were simply not important.

Other models

Supra also released a v.32 version at the same time, but it seems to have been fairly uncommon if it was ever really available. Mentions of it disappear by late 1992. The 144 LC was a low-cost version that lacked the alphanumeric display and replaced it with conventional LED indicator lamps. They followed up the 14400's with the SupraFAXModem 288, the first consumer v.34 modem, and then a series of various versions with different features. The SupraExpress was a low-cost series that scaled to lower price points, housed in an all-plastic case and lacking most of the indicator lights.
