(1) Set up a 9600bps connection between two Couriers.
(2) Send lots of zeros so that the compression algorithm in the modem has 
    something to compress.

The HST uses a 9600bps modulation scheme, and 14.4kb/s claims are for 
modulation speed * compression ratio. If you are mostly using it to 
download archived files, you will get 9.6kb/s, as the data is already 
compressed.
