Re: [hylafax-users] Errors on DeVolo Modem (Microlink)

Hi All,
I'm having troubles in fax reception with a Devolo/Microlink Modem
configured using the Elsa-microlink template.
Is this a different server or did you ditch the ISI modem?
I received the following error which is absolutely new to me.
Do you have any idea on what could it mean?
The bad thing here is that the sender's machine reported
a succesful transmission while it was not!!!
Thank you very much.
Bye.

The first curiosity here is that it takes two DIS cycles before the
remote accepts it, +FCO (when we enter Phase B).

The modem counted 1214 lines, by the way. So there seems to be some
discrepancy between what the DCE is relaying to the DTE and what the
DCE is receiving from the remote DCE. It's possible that the DCE is
just counting EOLs rather than counting lines of image data, and the
RTC is causing it to add some "blank" lines at the bottom. Anyway, not
a real problem, just a curiosity.

Nov 28 15:02:47.07: [ 8621]: RECV recv PRI-EOP (no more pages after
interrupt)
Although the "3F" (actually "FC") signal here indicates PRI-EOP. I've
never seen PRI used by a sender. It's possible that PRI-EOP was
misinterpreted by the DCE because it didn't check the CRC. Anyway,
PRI-EOP indicates that it's the last page of the documents to be sent,
but if a human pushes the "continue" button on the fax machine we
should start again at phase B (an ugly way to send multiple
documents). PRI is not for use with automated systems.

Nov 28 15:02:47.07: [ 8621]: RECV send MCF (message confirmation)
This is correct. We did get the message properly. But, as you
mention, I don't see an +FHT: report showing this signal transmission,
so I really don't know how the remote got "confirmation".

First off, we *did* actually receive the data properly.
SaveUnconfirmedPages in HylaFAX CVS HEAD (to-be 4.2.0) would at least
keep that data from being deleted by the server. However, we did not
send confirmation of the receipt, as far as the modem reports.
Is it possible that this modem is actually performing ECM "behind the
scenes"? Only then can I imagine how this occurred (MCF was sent
during ECM protocol, which is hidden from the DTE, and so the DCE has
already sent MCF by the time it tells us PPM and then ignores our
subsequent MCF).
