First of all Andreas, excuse me for the first wrong comments. I had just

Can you try build Hylafax from CVS? Your version contain a bug -- it
violates fax protocol and sends RTC (bit sequence, indicating end of
the page) multiple times. With some fax machines this leads to RTN failure, but
maybe it can also lead to the underflow error for some modem/remote fax
machine combination? Also check if the flow control is setup properly.
