    I have a Gateway M675 running XP Pro. Up until the end of January I could receive and send faxes without problems, although I did much more receiving than sending. When anticipating a fax, I would take the phone line from my DSL modem and put it into the dial-up modem receptacle (is that what you call that part?), and it would answer automatically after two rings as I had it set up in fax configuration. Before the problem, I would be able to hear it ring and answer through the speakers. When the problem started, I didn't hear the rings. so I checked the phone line by picking up a separate handset and could hear the automated operator "If you'd like to make a call, please hang up and try again..." If I try to send a fax and switch the phone line over, it will pick up the line before I have a chance to send the fax, unless I time it just right. I tried doing a manual answer, and unless I timed it just right, the phone line was already picked up, or it would answer but not receive the fax, or receive just part of the fax, and would take much longer than usual and I receive fax error messages, such as "there was an error receiving the fax from XXX-XXX-XXXX", but no specific error was given in the Fax Monitor dialog box. Basically when I switch the phone line from the DSL to dial-up modem, the dial-up modem picks up the line after about 15-20 seconds it goes from dial tone to the automated operator comes on, just like when you pick up a regular phone handset but don't dial. I cannot hear this happening over the speakers, just if I "peek" in on a separate phone handset for a couple seconds at a time. By trying all variables, I found that the line will even be picked up if the phone line is put in when the computer is turned off.

    I tried doing a System Restore to a date prior to when the problem started, but Windows won't let me and gives me a message "Restoration Incomplete. No changes have been made to your computer" (the problem started just before an Automatic Update). I have cleaned up my Startup to all but the bare essentials. I have uninstalled and reinstalled the modem driver. I have uninstalled and reinstalled MS Fax Services. I have replaced the modem card. I have had the phone company check the line. I have tried using a different phone jack. I cleaned the phone line receptacle of the modem with a Q-tip and alcohol (I found there was literally a squished bug in there, but it wasn't even touching the contact wires). I have an Agere Systems AC'97 modem on COM 3. I ran a diagnostic on the modem, and it came back as functioning properly (as far as I can tell), here is the log

    If I try the Troubleshooting through the Help & Support it suggests that the COM port is turned off. In Device Manager, the modem is listed under Modems, but under Ports (COM & LPT), it only lists ECP Printer Port (LPT1), none of the COM ports. I'm totally stumped, and Gateway e-mail supports wants $300 and me to send them my notebook, which I can't do anyway because I use it to work at home. Am I resigned to either buying a separate ol' fax machine or an external USB faxmodem?

    Hi there and welcome,

    Fax? Oh, I remember that :rolleyes:

    Lol, sorry. Right, can we try isolating the fault a little. Can you uninstall the fax software and then see if it still has a mind of it's own? It seems like a job is queued somehow.

    If the phone goes off-hook with the computer off, the modem is probably toasted. This is a sign that the relay that connects to the line has died.

    So I would need to try replacing the modem jack itself?

    Nope, the modem that's attached to the jack. :)

    I tried that once already, installed a new modem (OEM part off eBay), and it made no difference.

    Well, I'd visually inspect the jack and the modem connection. If this happens with power off, it's most likely some sort of short, either on the modem itself, the wiring to the jack, or perhaps even the cable.

    Check the setup of your maodem with your manufacturers diagniostics. reset "auto answer = OFF".

    I doubt that would affect the behavior with the power off. ;)

    Some boards supply power to the modem even when the system is shutdown; this is how wake on ring is able to power on the computer. Check your bios to see if you have this option. If so, disable it.

    Have you tried the modem in another pci slot?

    Just wondering if this Restoration incomplete means something??

    It would seem to me there would be something that had been changed in the last couple weeks?

    What about removing some of the updates just prior to that date?

    Does the fax modem need a working filter??

    Just throwing some ideas out there.

    Modems are line powered from the Subscriber line, only the more sophisticated and not so good ones rely totally upon mains power. The feature allows for bell ringing on an adjacent phone, for purely audio purposes.

    If this were not so then the device would not meet the requirements of the BELL, BT or CCITT connection spoecification.

    The connection capability dates back to the days when a mainframe was virtually disconnected from the real world except thru a voice and data modem. The incoming signal indicated by the RI signal on the 25 way connector allerted the user to turn the modem on. It is part of the ASCII spec, under RS232.

    Hi there Wacor,

    No, I have a feeling that it is another couple of problems we are dealing with. We have a fighting hiding Trojan, the first few were called Ajax and Achilles way back in the 80s, but this one is very sneaky and has shown up a very large hole in Microsoft software, and probably Linux and Unix as well. I suspect Bill left it there to show that they could not get on without him.... It may even be in Win3.11.

    If anybody has a cd with win3.11 on it we can test it.

    I could give you the file name to search for but the filename parser in all windows and probably linux will not see it.

    The fact that the regedit dees it indicates somebody at microsoft has seen it, or made it.

    How do I start a new thread ?

    WARNING PROBLEM WITH MICROSOFT OS.

    The old convention under dos of using '?' to match a single character does not work under Windows, and probably linux (as the convention is not used.) The convention of using a <space> may work but with regard to tracking trojans and the like this convention is to easy to aviod, as control characters may be used to by the OS to mask OS builder's critical software.

    This has been reported to Microsoft.
