				  -------------------------------

But it doesn't help at all if you are transmitting something that is already
compressed, like UUCP files that are compress-ed, or ARC files on BBSs, or GIF
image files, or any number of other packed files.  The "compression" may even
worsen throughput in those cases, due to the overhead being added on top of
incompressible data.  Since almost all of the modeming I do that I need high
speed for (see above exmaples) is already packed, it is hype in my book.  But
for someone who does online screen editing via modem, it would be a great help,
on top of the error correction (which is also in software in the examples that
apply to me).  Each to his/her own...
