I am programming a C++ console application that connects to an external
modem using modem commands.

When using the modem command "ATDT<phone number>" (with dial command
modifiers), I get the "No dial tone" message. Please refer to this link
for details if needed: http://support.microsoft.com/kb/q164659/

The modem connection works fine otherwise.

If you know of anything that may have been overlooked, would be nice if
you could point me to it.

Thanks.

Cheerz,
Denzil

Denzil, I suggest you throw out the C++ development work and start with the
HylaFAX or mgetty software, available at sites near you on an open-source
license basis. Then take a look at using proper setup commands, such at
"at&m1" in order to turn on the speakers so you can hear what's gooing on.
You can even use HylaFAX to test out the modem itself for the ability to
send faxes, which will confirm that the modem itself works and which will
keep it in the proper, pre-configured state your software may expect.

Nico,

Thanks for the details and I will have your suggestions in mind. The
environment for development is fixed (not decided by me).

That said, my issue is now resolved. It was faulty hardware that was
the cause of the problem.

Thanks,
Denzil

Cool. I find the "faxsetup" command from HylaFAX to be a really excellent
modem tester: you might like it for future use.

Noted. I should try out "HylaFAX".

OT - Are you aware if the eFax service is based on "HylaFAX"?

Thanks,
Denzil

Last I checked, it is. It made me laugh when a company I worked with wanted
to switch from a bunch of scattered fax machines to using eFax, and I said
they could use my old software notes on using an internal service. They were
much more excited by eFax advertising than by my old flat text notes on how
to use HylaFAX.
