Hi Dan,
From the log, it looks like something wrong is in the modem software. I
have been adding a V.27ter modem to the FAX software, to do the slow
2400, and 4800 bps FAX modes. I've been busy with other things the last
couple of weeks, but I am finishing this off now. I have also made the
existing V.29 modem more robust on bad lines. When I get this released
(should be this week) I will look into the issues that you and some
others are having. It seems the current software works OK with some FAX
machines and not others. Perhaps I need to make it more tolerant. :-)
Regards,
Steve
