Modem compression is less efficient than application level compression
for two reasons:
- Modem buffers are smaller, limiting the compression rate
- A pure data stream (e.g. an active file) is more compressible than a
data stream frequently intermixed with TCP/IP headers.
IMHO modem compression is much less useful nowadays than in the past,
when modems mainly ran text terminal connections and application
compression was uncommon (except for UUCP).

ISDN isn't that fast either. Furthermore, fat pipes are not an excuse
for inefficient protocols IMHO.
