- Yikes! And wrong.
-
- DELL does not know about VJ header compression. The Netblazer certainly
- does. As such, you will see significant improvements in interactive
- performance.

- Now if I could figure out the algorythm for the flipping modemcap.txt
- file and how you really talk to modems for dialing and configuration. There
- are some nasties in there that I've yet to figure out.... ;-)

- I do agree, however, that in general the Netblazer is a really nice product
- for this use. It does the job and does it quite well. Multi-month uptimes
- aren't rare at all.
