flexfax: Perfect Blank Faxes

[msw@cluedin.com (Michael S. Weiner (Doc))]

My mission critical fax application is broken and I would
appreciate any help I can get.  I've been reading in this group
for sometime and have gotten lots of useful info tho I haven't submitted
any questions.  I've searched the FAQ and archives without gettting
a clue.

PROBLEM:  Today I replaced my USRobotics Sporter 33.6 modem
with a Multitech MT5634ZBA.  I also upgraded the Hylafax software
from V 4.0pl0 to V 4.0pl2  using the SCO OSR5 binary version
built by Tim Rice.  (I'm on a SCO OSR5.0.5 box).
Since the installation faxes are being received apparently
successfully -- none of the Phase B and C errors I used to
frequently get and the speed of transmission is improved
(about .6min/page).    HOWEVER, there is no "information" on the pages
when viewed (either with my ghostscript or the windows95 and MAC
viewers of the folks to whom I forward the *.tif files) --
faxes processed prior to the upgrade are normal.
The "blank pages" are not entirely blank looking something like
the copy of a blank page on a copier on which dark setting
was turned up some -- there are some thin faint shadings
on the pages.

POSSIBLY RELATED ANOMOLY:
faxstat gives this error:
Login failed: 550 Cannot set privileges
But I'm inclined to think this isn't significant in view of
the following:
