I am having a severe problem with my modem being able to recognize a
dial tone
I have been trying to fix this for >10 hours and at this point am
really frustrated...
Here is the story -
Last weekend, the modem got unplugged. This should be no big deal since
we live in an
area that looses power frequently....
We tried to connect to the internet before realizing the modem was
unplugged, and recieved
an error. The modem was plugged back in, and it said "there is no dial
tone detected,
please check to make sure that the modem is connected correctly"

* uninstalled the modem, and reinstalled it with the original drivers
* Checked to make sure that the phone line was connected correctly
I am able to connect through the same phone line with a laptop
computer running windows xp with an internal modem.
* Unchecked the wait for dial tone box
* Forced dialed with the AT X0 command. I have also used the init
settings
of xxx, x3, ,,,, and several others. I can get the computer to dial
without detecting a dial tone first, but it wont connect even when
dialing
* Ensured that I have no port errors
* Tried both com1 and com2 mutliple times
* Uninstalled and reinstalled DUN
* tried a different modem
* Used hyperterm to try to dial - same problem, no dialtone. I can
force dial,
but get no connect
* tried both jacks on the back of both modems
* checked to make sure that my cables are in good working condition,
and replaced them
* reinstalled the winsock.dll files
* chekced to make sure there where no communication programs running
* no port conflicts
* verified my TCP/IP settings
* I have client for mircrosoft networks, microsoft family logon, dial
up adapter,
and TCP/IP in the network configuration

It is a windows 98 computer, with an external modem. The two modems I
have tried are
US robotics 36.6 and a CNet v.90 56k externally connected through a
serial cable.

In the modems control panel, I am able to run the diagnostics on the us
robotics modem
and get no errors, eith the CNet modem, it tries to run the
diagnositcs, and states that
there is no dial tone. I can see that the computer is communicating
with the modem, as
the lights turn on, and blink.

I always get the error, "there is no dialtone or your modem is not
connected correctly"

I had this same problem last august, and spent many days trying to
correct it. I remember
that once I got it working it was a computer problem, and not a modem
problem.
I don't remember for the life of me what I did to get it working,
(teaches me not to
write these things down!) At that point I thought that it was a broken
modem, purchased
a new one, and had trouble with the new one. Once I got it working, I
remember thinking,
that it wasn't a broken modem, that the old one would still work, and
maybe I should return
the new one....

For the life of me I can't figure this out...

Please help if you can

adapters or telephone cables/adapter mixed up? Different voltage/current
supplies and different wiring styles may not be compatible.

Sorry if another incomplete post is present - I tried cancelling it.

Nope - the power cables are correct. I had just one modem until today,
when I tried with the second one....

the wrong supply may power up the modem, it will likely result in the
problem you're getting (and so could using the wrong telephone cable). In
case you're wondering, nope there's no other clue to this.

Given that you've already spent a while attempting to repair the set-up
what's wrong with testing the modem/cable/power supply on another machine
and if it works fine there, performing a back-up, format and reinstall on
your win 98 machine?

Reformatting the system is like cracking a walnut with a sledgehammer.
The OP has an external serial modem. The easiest thing to try before
anything else is to type the following command at the DOS prompt.

echo AT L3 M2 H1 > COMn where n = 1,2,3, or 4

This turns on the modem's speaker at max volume and takes the modem
off-hook. The OP should hear a dialtone.

The same command sequence can be executed in HyperTerminal.

To hang up, type ...

echo ATH > COMn

I agree that its a last option but given there's already been over a day
spent figuring out this problem with no result, if a test of the modem on
another machine (or now even using DOS on this Win 98 machine) confirms the
hardware is working fine and given that so many things have already been
reinstalled (modem drivers, DUN etc), might that not be the quickest and
simplest way to go in the long run? I've had fairly standard Win 98 systems
reformatted and reinstalled in under 2 hours of "donkey work" (allowing the
format process to progress on its own overnight beforehand). The machine
often runs much faster as a result too.

The OP says (in several newsgroups) that she has the same "no
dialtone" problem with two external serial modems. I can't imagine
what kind of software issue could cause this. IMHO, the very first
thing to do is to determine whether a dialtone actually exists. The
"echo" command would be an easy test. In fact I just did it in less
than a minute. Ask yourself, if the modem cannot draw a dialtone in
response to a *DOS* command, especially one that is internal to
command.com, then what will be achieved by reloading 200MB of Windows?
I can run this exact same test from a bootable diskette containing
just the three basic system files, command.com, msdos.sys, and io.sys.

If you don't hear a dialtone, you can confirm whether the modem is
receiving data from the COM port with a dial command such as ...

echo AT L3 M2 X0 DT your_own_house_number > COMn

If you hear the DTMF digits, then the problem must be between the
modem's DSP and the phone line.

Next, try listening for DTMF digits, and a break in dialtone, on a
parallel handset while the modem's speaker is turned off:

echo AT L0 M0 X0 DT your_own_house_number > COMn

Among other things, this will tell you whether the modem has managed
to take its hook relay off-hook.

If the modem has an electromechanical hook relay (I suspect the 33.6K
modem is one of these) then you should be able to hear it clicking
when you send a pulse dial command:

echo AT L0 M0 X0 DP your_own_house_number > COMn

This makes no sense to me. AFAIK, the Control Panel Diagnostics do not
attempt to draw a dialtone. They merely interrogate the modem using
informational commands such as ATIn and AT+FCLASS.

Finally got it working. The modems where both bad. I bought a new
modem that also didn't work, exchanged it, and now am up and running
with a new modem. Thanks for the suggestions
