mgetty Fax Reception

Post by Maurice Rei » Sun, 31 Dec 1899 09:00:00



I've got as far as dialling into my Linux server anf getting reliable
PPP connections and console logins, which isn't bad.

However I can't get the modem to answer fax calls. It doesn't negotiate
sucessfully.

It's a 3COM USR 56K Voice Faxmodem.

any pointers would be gratefully received.

Maurice.

  You should increase the log-level of mgetty and then youll probably
see whats going wrong.

If you follow the standard how-to's, there's often a -D flag suggested
to the mgetty daemon, which restricts it to "data only".  Check your
inittab entry (or where ever you start and configure mgetty) to make
sure that this flag is *not* present.

Otherwise, as was also suggested, bump up your debug level.  (-x 9).

1. mgetty for fax reception

I've got my mgetty set up now to work with fax AND data.  Seems to be OK.  The
only problem is that when I send it a fax (from a computer at work) the sending
side reports that the line noise is very high - almost unusable it complains.  Now
I know that the line quality is very good and that with voice and data there's
absolutely no noise, so it's something the modem's doing in fax mode.  Can anyone
think of anything it might be?

I have the modem (a 14.4 data/fax modem) set up to use compression and
correction by default and to use 19200 (because it's a Rockwell chipset).  The
sender claims that the fax was transmitted at 9600 baud...dunno why - maybe
the send side can only handle that.

So - if anyone can think of any reason for the noise, please mail me directly at

Thanks.
