After installing 4.3.1 I again noticed that the ECM was not
being utilized, as well as the failure to convert to 2-D MMR
(in class 2.1 mode).  Then I upgraded to 5.0.3 to see if this
would would the problems, but the same behavior was observed
(again in class 2.1 mode).  So then I went back to 4.3.0 where
at least the conversion to 2-D MMR was functioning (again in 
class 2.1 mode) but ECM was not.  While using 4.3.0, I decided
to try class 1.0 since class 1.0 bypasses the modem firmware
The included log file represents that attempt.

But now I'm back to using 5.0.3.

How does one explicitly enable ECM?  In my sendfax.conf file, I
have:

DesiredEC: 2

This should enable ECM.  To disable ECM, this would be set to zero.

You are correct.  At the very beginning of a transmission, just
after the dialing tones, the sendq/q* files shows:

desiredec:0

But, unless I am mistaken, I do not disable ECM in any way.  No "-E"
is used and the sendfax.conf is as above.

But using 5.0.3, the doneq/q* file also shows:

dataformat: 1-D MH

With 4.3.0, sending the same fax, this is:

dataformat: 2-D MR

That is the other problem that seems to have arisen with 4.3.1
and 5.0.3.

In conjunction with "make install" I use a utility called installwatch
that enables me to record where all files are placed.  Before a new
install I completely remove the old one, including any symbolic
links.
