[hylafax-users] How to remove "No carrier detected" error, PBX

[Lukasz Szybalski]

Hello,
I am trying to remove the "No carrier detected" error from my system.
Since i need to dial 9 before i can send from analog fax i added this
to my conf.ttyS scripts.

ModemDialCmd: ATDT9,%s
From what i read this command creates a dial tone, then sends 9, and
then a phone number.

Is there a website somewhere where there is more commands and their
explanation of these commands.
I am looking for a Dial command that will do 9 + pause + phone number
The pause will make sure the dial tone is present.

How would this command look like?
ModemDialCmd: ATDT9,PAUSE,%s?????

Thanks,
Lucas

Most modems will interpret a comma ',' as a pause. Try addind more than the
one you presently have in your ModemDialCmd.

Most modmes when dialing with ATDT will *wait* for dialtone before
dialing any of the digits specifed. If it doesn't have dialtone, it
won't even get to doing 9,PAUSE, etc...

Most modems also have a setting which enables it do dial "blindly", not
waitin gfor dialtone. You'll have to consult your modem docuementation,
but on the old Rockwell I had, it was "X3". In that case, I had:
ModemDialCmd: "ATX3DT9,,,%s"

This would instruct the modem to *not* wait for dialtone, and start
dialing 9<pause><number>

I have tried that. But i do get an error:

device 1, setting:
ModemDialCmd: ATDT,9,W,%s (wait, dial 9, wait,wait for tone, wait,
dial string)
ERROR: No local dialtone

It failed so it try's to send it again. This time on device 2 with settings:
ModemDialCmd: ATX3DT9,,,%s (dial 9, wait 3x dial string)
ERROR: No carrier detected


Now, I read somewhere that i could include:
"
#We can append the "@" symbol to the dial string so that
# the modem will wait 5 seconds before attempting to connect
# and return result codes that distinguish between no carrier
# and no answer. DT9%s@"

I have tried that but it gave me an error on every file.( either no
carrier/no dial tone with no particular order.)

What is the difference between "no dial tone" and "no carrier detected"?
Is anybody using "@" in the dial command?

What other commands, or combination of commands could i try?

Hi Lucas,

Try using Minicom and sending the AT commands direct to the modem. If this
works then you know the issues are with HylaFAX... If not, then the issues
are with your pabx/modem (which is most likely).

Those errors that i talked about are happening on 1/10 faxes. Which
means there is no particular pattern that i could test it against? I
assume if i do what u just told me than i should see everything
working?!

I do it by

Post by andrew rinaldi
minicom

AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
OK

Then type:
AT and get :
OK


Is that correct?

Hi Lukasz,

Apologies for the delayed response..... yes, you are correctly sending AT
commands to the modem and getting a 'OK' response.

Now try sending the dial command that you want HylaFAX to use.....
ATDT9phonenumber or ATDT9,,,,,phonenumber (replacing the text 'phonenumber'
with the number you are trying to call - I suggest that you use your cell
phone or something else you can hear ring during this test).

The purpose of this test is to ensure that you can correctly dial through
your PABX with your modem.

You probably want to read the AT commands manual for your modem.
