If you're fetching WWW pages, the modem compression is used *alot*.

With 15+ images and pages being fetched via my 28k I frequently see more than
7k/s which requires a serial speed of around 70k+ - OK its not 115200, but
with a 57,6 you would be limited to 5k/s.

Then again, my machine (a RPC) is running as a server, and its unlikely 
you'd being using an A4000 in the same situation.
