A GVC Modem 28,800/33,600 Internal is not faxing  ! The proble is that the modem is seen and configured but when the phone dials remotly it only waits one ring and then disconnect ! If you will tell me initialisation string, well I have tried Quicklink fax wwhere you can manipulate the initialisation string and I have the same problem ! I have downloaded the latest drivers and all but the problem still persist ! It is quite weird and funny enough I doubt whether it is the modem as if i dial up the Internet with the right initialisation string it rings fo ever and connects fine !

superfranco,
Are you using the dial up adapter for your internet connection?
If so, the modem you have selected should be the same one for your fax application.
I hope this helps,
Ralph

The modeM IS WORKING under internet and yes i am using the windows 95 dialer ! !

I solved the problem in quick link fax, the dial string was AT4XDT and i made it ATDT. Is there a way to change that dial string in the registry ??  THat is why My microsoft fax does not work ! Let me know ...

superfranco,
With modem driver in hand, one way to do it is:
Remove modem listed in device manager.
Shut down windows.
Remove modem from machine.
Restart windows and autodetect new hardware.  That should remove registry entries.
Shut down again.
Replace modem.  If modem is PnP, windows will detect/prompt for driver.
Regards,
Ralph

Rmmarotta that was all tried time and again ! You have to understand that this modem is fine, it is set up correctly, ( i am a Microsoft Certified Professional after all ) so the problem here is deeper than that ! It is the fact that one can not control the initialisation under Microsoft Fax ! I think we must look under that direction !

Oops...
sorry superfranco.  I failed to look at your customer info before I posted.  You're probably much more qualified than I to diagnose/correct that modem problem.  Please reject this answer so someone else can assist you.

superfranco,
One other comment:
It seems that if the modem is operating properly for internet access, then windows has done its job correctly.  As I understand it, windows configures your modem with its driver for any program that accesses it.  Perhaps it might help to re-install the fax under windows setup.
Cheers,
Ralph

superfranco,

Could be that the modem has received some incorrect settings. Try reloading the factory defaults with the command AT&F from a terminal program. It sounds as if one of the S-register settings is out of whack.

Hey Jmlynek, thanx for teying, that also was tried time and again and all other kinds of strings where tried as well. That is what is puzzling me ! the moment I try Microsoft fax, boom remote ring only once, with Quicklink fax it does fax but bottom of the page is spoilt !!

Sorry but we must try through the registry to give Microsoft fax an dial string of ATDT !! I think that is the solution but I don't know where that entry is !!

superfranco,

Look under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem. You'll find all the settings there.

Good luck

Jmlynek:

I am sorry, your registry pointing is correct but it still does not solve the problem ! I have tried all, but still Microsoft fax only lets the remote phone ring once and that's it, it then reports a send fail ! I tried another fax modem, and no problem it fax wonderfully !

    I'd say if it works with quicklink, then the modem is fine...  You say all you needed to do with quicklink is change AT4XDT to ATDT?  That worked?  And you're dialing the same number with Microsoft Fax?  And this happens with ALL fax machines you send to?

Your modem is FINE!
Your problem is with the CLASS of fax modem you have selected,
There are 4 fax Class'.
Class 1
Class 2
Class 2.0
FaxBios (obsolete)

Chances are you have selected Class 2, and you need Class 2.0.
Or Vice-versa, (2.0 was developed by USR, they tried to pull a microsoft)
If all else fails, use Class 1.
Go into your modem, diagnostics, more info...
It should tell you the type of Fax class your modem supports.

Inside your modem configuration, there is a setting for the fax class, but it the fax software generally overrides this setting.

May the Force be With You!

  Really?  I always assumed it would just default to whatever the connections was.
