- First, let me explain that the 8-1 (or better) is certainly a reality
- now. All you need to do is create a highly compressible file (or use one
- of the modem manufacturer's super-compressible test files), make a
- connection between two compatible modems with DTE rates of 115200 and DCE
- rates down about 12000 or 9600, then transfer the file.
-
- I've done it. I know the answer. Now, you do it and you'll know the
- answer since you won't believe the rest of us.
