this is what i think also. Unfortunately i have now knowlegde about the
fax protocoll, this is just from my experience and what i have read on this
list.
(i think there is some problem in the class 1 driver of hylafax?)

i read on this list that commercial software often uses class 1, no matter
what
you configure. unfortunately i do not remember where. maybe search for
"winfax"
in the archives?

i have access to Winfax Version 8/9. Do you know software which can monitor
the
serial line? would this data be of any help for you?
