Unfortunately I cannot inform them.

That's OK, there is no urgency to resolve this issue.

BTW, I also tried Class 1 and got the following:

Ooops! That's just the next Hylafax bug :-) It fails to interpret short (3
bytes) information field of DIS frame. Yes, I already know how to fix this
:-)

You asked that is error-free fax software? Now you know the contrary
example :-)

I'll try Class1 again when I apply fix for the bug above.

Unfortunately no.

Perhaps, but I checked the T.4 data, they seems to be OK (although the last 
time I told you just the same :-)))

I also forwarded this to the mailing list because the problem seems to be
interesting for its subscribers.

Hope to hear from you soon,
Dmitry
