I've found it useful to make some of the links on sgi.sgi.com use
compression and some not.  Those links where compressed news batches are
most common seem to benefit from having it turned off.  Others where mail
and file transfers dominate benefit from having it turned on.  It is easy
to switch by adding the necessary commands to the phone number, or in HDB
UUCP, by choosing differing ACU-types/Dialers-entries.  One often has to do
extra fiddling for sites that have odd combinations of PEP tone
presentation, v.32, PBX delays after answering and before presenting tones,
and so on.  A little more hacking to select the correct compression is not
a big deal.
