- This item might be old news to some people but I find the test results
- informative enough. On the Oct 24/95 issue of PC MAGAZINE, the top selling
- 28800 kbps modem brands (at this month) were tested and their performance rated.
- The modems tested were AT&T DataPort Express 28.8, Best Data SmartOne 2834FX,
- Cardinal 28.8 External Fax, Hayes Accura 288 V.34/V.FC + Fax, Motorola Power
- 28.8 Data/Fax, Multi-tech Multimodem MT2834ZDX, Practical Peripherals Class 288
- MiniTower II V.34, SupraFAXModem 288, U.S. Robotics Sportster 28.8 V.34
- Faxmodem, and Zoom/FaxModem V.34X.
- The modems were rated not only on transer speeds but also on six categories
- which are important to home users (which people tend to overlook when
- considerng a modem to purchase): setup, design, software, performance, service
- and reliability, and overall value.
- Setup - a modem should provide an easy-to-understand setup guide, install
- effortlessly, and connect with the on-line services on the first try.
- Design - includes placement and durability of switches and buttons, status
- indicators, and overall size and sturdiness of teh modem.
- Software - a modem had to provide startup kits for the major online services
- such as AOL, Compuserv, Prodigy, as well as beeter than average communication
- and fax software, including net browser, special function software.
- Service and reliability - modem's warranty and the vendor's technical support
- policy (toll-free call, and extended technical support hour).
- Performance - speed and reliability in the ff operations: fax, telephone-network
- simulation, throughputs vs. file type transfers.
- Overall value - encompasses all of the above, weighed against the price of the
- modem.

- Benchmark Test Results.
- The computer setup used for testing was a Dell 486/33 ME with a Hayes dual-port
- ESP Board (NS 16550 UART). For throughput and telephone-network simulation
- tests, the software used was XFR (Satchell Evaluations), and for the fax test
- the software used was WinfaxPro.
-
- 1. Throughput vs. file type. Five data type (highly, moderately, and slightly
- compressible graphics, incompressible file, and combination file) were
- transferred unidirectionally as well as bidirectionally to test for
- effectiveness of V.42 error correction, V.42bis compression, framing overhead,
- and dictionary.

- 2. Telephone-Network Simulation. Measures the effectiveness of modem's V.42
- error correction algorithm, signal converter, and firmware in handling
- simulated line conditions. 168 line conditions were used which are most likely
- to occur in PSTNs.

- Hayes Acura and Practical Class modems could not complete the fax test because
- of incompatibility of Rockwell chipset used. Using version 1.3 of the code
- fixes the problem.
