This "shootout" was designed to provide an indication of how the USRobotics Sportster (92 MHz model) compares to the well-regarded USRobotics Courier (V.Everything model) over a good connection. A ZyXEL Elite 2864 was included as an additional reference point. Both the Courier and the Elite were external units on a real 16552 UART; the Sportster was an internal unit. All COM ports were locked at 115.2 Kbps.
The shootout consisted of sending and receiving a compressible real-world ASCII text file of 188,389 bytes (an old Agora text version of the Navas 28800-56K Modem FAQ) between a Windows 95 system (Intel 486DX4-100) and an FTP server. Windows 95 DUN (Dial-Up Networking) was used for TCP/IP, and all modem connections were at 28,800 bps. The tests were run late at night in order to minimize disturbances caused by load on the network and FTP server.
All results are measured in Kbps, rounded to two significant digits:
The winner was the 92 MHz Sportster by a nose over the Courier V.Everything!
