receive fax image problem




I'm using HylaFAX v4.0pl2 on Solaris 2.6/ultra 60 using gcc 2.8.1
(with the hylafax-gcc-2.8.x.sh patches) and a multitech 56384zbav
modem.  I switched to a Central Data serial port card with full
bidirectional hardware flow control to avoid the buffer overruns I had
been experiencing with the internal ports, but I still have a problem
receiving faxes.  I had blamed the problem before on the buffer
overruns, but that excuse is gone; no error messages now, and good
flow control).

When I receive a fax, the log looks fine, the image file gets created
and I receive email about it.  However, the fax seems screwed up, as
if horizontal hold on a TV was misadjusted (i.e. as if data is missing
randomly from scanlines which then get shortened and dont all start at
the left.)  I'm viewing it using a ghostview that is known to work.

When I run fax2ps by hand, I get a string of messages like this:

    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 2 (x 1246).
    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 3 (x 1246).
    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 4 (x 183).
    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 7 (x 1246).
    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 8 (x 1246).
    /tmp/fax2ps015635: Fax3Decode1D: Bad code word at scanline 9 (x 1246).

Everything else works fine: sending faxes, adaptive answer and
faxgetty login, uucp, tip, etc.

Help!
