Re: [hylafax-users] No carrier detected

Thanks John.
I've tried to change my setup to reflect your

ModemSetupDTRCmd

setting, but it doesn't solve my problem :(

I post here my config.ttyUSB0.

Hi:
I am sorry I can't give you specifics because I don't know the details
of that modem, however, it seems that in general, the setup for
detecting the carrier is not correct. This is usually done by
configuring the 'ModemSetupDTRCmd' and the "ModemSetupDCECmd"...Here
is how my setup is accomplished in config.ttyACM0:

For my Conexant RD02-D400 (AKA Dell USB modem)
#
# Configuration for a Rockwell RC288DPi-based Class 1 modem.
#    Hayes Optima 28800    firmware rev ???
#    Microcom DeskPorte 28.8S firmware rev V1.100K-V34_DS
#    PPI PM288FXMT      firmware rev 1.57
#
# Note that the modem does not lock the line rate for fax
# receive (at least not the PM288FXMT); but not sure whether
# current flow control settings are maintained or if it
# switches to XON/XOFF (testing host was too fast to see).

You can compare this against your config file...noting the ModemSetup section...
Perhaps you can post yours here?

Yes, config.ttyUSB0.

Modem work perfectly in receiving direction, and in calling direction place
the call, remote fax machine answer and start handshaking, but hylafax reply
with "no carrier detected".

Thanks
Daniele

Hmmmm, how did you install the USB modem?
config.ttyUSB0 ?
When I installed my USB modem, it was under config.ttyACM0.  My modem
is a Dell USB, with a Conext chips set.

Hi all, I'm using hylafax 4.4.4-7 on an ubuntu server.
I'm testing it with a usr modem:

Dec 12 17:16:33 ubuntu-fax FaxGetty[18764]: MODEM USR U.S. Robotics 56K FAX
EXT Rev.
11.16.63/Configuration Profile... Product type CTR-21 External Product ID:

11.16.63 DSP date
     3/28/2005 DSP rev 11.16.63

I'm receiving fax very well, but I can't send them, I suppose is a modem
problem.

The error that I can see is:

FaxSend[17607]: SEND FAILED: JOB 3 DEST 00116319664 ERR [2] No carrier
detected

This happens with any destination.

I've tried to make manually the call, with minicom and ATD command, and
remote fax answer and begin
handshaking.

Maybe I need to change my /etc/hylafax/config.ttyUSB0 configuration?

Thanks
Daniele
