flexfax: Document was encoded with 2DMR, but modem does not support this data format

[Haral Tsitsivas <haral@unisol.com>]

I have been using Hylafax on and off (after fixing the Phase B error
for my Sporster 56K modem) for a while (outgoing only)...  Today, I tried
to send a FAX and it failed with the error:

Document was encoded with 2DMR, but modem does not support this data format

I have sent FAXes to that machine before from Hylafax and I didn't have 
any problem.  Why is there a problem now?

BTW, I am using Hylafax v4.0pl1 on Solaris 2.6 (the binary version 
from SGI's ftp site for hylafax-sparc-sunos5.5-v4.0pl1-pkg)...

Here is the complete fax log transcript:

BTW, looking at earlier logs, I noticed that although the remote machine said
2-D MR was best, Hylafax was using 1-D MR...

The log from a month ago showed:
