flexfax: RSPREC error but fax OK?

["Dr. Detlev Reymann" <D.Reymann@geisenheim.mnd.fh-wiesbaden.de>]

Hi,
I am using a "3Com U.S. Robotics 56 K 
Voice Faxmodem" to use it with my Hylafax-Server (Version 4.0p12) on a linux 
box (SuSE 6.0).

A last problem is left creating the config-file for my server.

Although a fax is send correctly I get the following error:

Apr 14 19:05:55.87: [  681]: SEND send EOP (no more pages or documents)
Apr 14 19:06:13.77: [  681]: --> [7:+FHS:51]
Apr 14 19:06:13.77: [  681]: REMOTE HANGUP: RSPREC error/got DCN 
(code 51)
Apr 14 19:06:13.78: [  681]: SEND: RSPREC error/got DCN; Giving up after 3 
attempts to send same page "docq/doc16.ps;01", dirnum 0

What does that error message mean?
And is there a configuration detail, where I can correct this?

Thanks in advance

Detlev
