Subject: corrupted tiff files
Date: Sat, 15 Jun 1996 07:00:49 EDT
From: "Thomas B. Clark"
I am a recent convert, and LOVE Hylafax;
unfortunately, I still have not successfully received
a fax, although I can send them normally.
This is additional information about the problem I
already posted. The TIFF files are actually corrupted,
since another program does not recognize them as TIFF.
System: Sparc 20, Solaris 2.5
Serial port: /dev/cua/6 (MAGMA serial board, no
parameters preset)
Modem: SupraFax 28.8
Email received from Hylafax:
recvq/fax00010.tif:
Could not open recvq/fax00010.tif; either not TIFF or corrupted.
ReceivedOn: cua_6
The full document was not received because:
Normal and proper end of connection

The resulting TIFF were considered "corrupted" because they had no valid
data in them (yes, the error message could be more informative). You need
to figure out why you're receiving no data or garbage data. Frequently a
problem such as this is caused by the wrong RecvFillOrder or a host-modem
flow control problem. You might also try disabling copy quality checking
in the host so that you capture the raw data from the modem--you can then
look at it with some of the TIFF tools to, for example, figure out if the
bit order is opposite to what is expected.
