- Here is some statistics that a USR engineer did (independently on his own)
- between the normal Sportster and the Winmodem on two different machines.

- These are the results from testing my modems in my computers with
- my software at my house. What you get with your computers and
- your software at your house can/will be different. Test System #1
- is a 486SX-25 with 4 Megs RAM, running Windows 3.1 and Procomm
- Plus for Windows V1.0. This is the oldest and slowest Windows
- machine I could find. Test System #2 is a Pentium-90 with 16
- Megs RAM, running Windows for Workgroups and Procomm Plus for
- Windows V2.0. The Host/Reference System is a PCBoard BBS using
- the DSZ.EXE transfer protocol driver. Ymodem-G protocol was used.
- The Reference (Host) modem is a Courier I-modem. The files used
- are the industry-standard EIA throughput testing files. Both a
- Sportster and a Winmodem were tested. Both modems were locked at
- 28800 with the &N14 command. (The 4X04 file is pretty much the
- same as a ZIP file, this is the one that will be important to
- most people.)

- My observations:
-
- 1. The Winmodem documentation is obviously correct in suggesting
- a 486/Pentium machine. (I'd lean more towards the Pentium,
- myself.)
-
- 2. A 486SX-25 is not a very good Windows machine, even for a
- "regular" modem. <G>
-
- 3. On the slow machine, compressable file throughput was lower
- than expected for BOTH modems, but compressed/zipped files
- still transferred at the usual speeds expected from a 28800
- connection, without any errors or unusual operation.
