Modem genius wanted

I'm at the end of the road on this and perhaps there is someone out
there who may have a clue why I'm having this problem.

I have a couple of modems that I've tried, with the same result.

I'm talking to the modem using AT commands and the serial port.

I'm using BOTH hyperterminal and visual basic in my attempts.

Here's the problem ---

I can get an OK response on any valid command I send to the modem and
it doesn't matter what mode the modem is in.....(data, voice or
command).

BUT

I CANNOT get any response to my dialout command (ATDT13174446354 & cr)
(for example).

The modem will get dial tone, call out and I can answer with no
problems whatsoever, but I don't get any AT response......(like RING,
BUSY, NO ANSWER etc).

I am not talking to another modem.....I'm calling a telephone number.

(But it's my understanding, that doesn't matter).

These are "connection progress" messages I should be getting from the
originating modem to it's PC and after all. like I say, I get an OK on
any other good command.

Thanks so much for any help on this.
 
I got some bad information from someone, it looks like.

I've been expecting to see RING from my (originating) modem, when it
appears that you only get a RING from an incoming call.

? (can you confirm?)

I do now see a BUSY and RING using hyperterminal but like I say I've
been spending days thinking in terms of getting RING from an outgoing
call.

I need to look closer at those S registers -- it may be my only way of
doing what I want.

Check the ATXn setting. That lets you choose how detailed dial results
are.

You really need an AT command set, and to read the thing end to end! In
the old days, modems came with a proper manual (on dead tree) that explained
all this in gruesome detail.

Have you accidentally stored settings that will turn off some of the
responses? You used to be able to adjust the level of reporting from the
modem. From my old modem manual ...

ATQ0 Result messages turned on <- You probably want this
ATQ1 Result messages turned off

ATV0 Result codes as numeric
ATV1 Result codes as words <- You probably want this

ATX0 Result codes: Basic. Dialling is blind, regardless of dial tone.
"CONNECT" will be returned on getting a remote modem.
ATX1 Result codes: Extended. Modem now indicates connection speed in CONNECT
response, e.g. "CONNECT 1200" (haha! How quaint ...)
ATX2 As X1, but with dial tone detect
ATX3 As X1, but with busy tone detect
ATX4 As X1, but with busy AND dial detect <- Hello, this looks good!

Modem codes (not exhaustive, but the ones you'd need)
0 OK
1 CONNECT (you won't see this for voice use?)
2 RING (incoming)
6 NO DIAL TONE
7 BUSY
8 NO ANSWER
33 FAX

Newer modems can, I think, detect "VOICE" as a response, but I don't
know how they manage it. "It's sound, it's not a modem, it's not a fax,
it's not call progress tones or DTMF, therefore voice?"
problems whatsoever, but I don't get any AT response......(like RING,

RING is in response to incoming calls. It keeps saying "RING" whenever
the modem detects an incoming ring.
These are "connection progress" messages I should be getting from the
originating modem to it's PC and after all. like I say, I get an OK on
any other good command.

Try ATQ0 ATV1 ATX4 and see what happens. Maybe you'll get more responses back?

It's been a while since I messed with any of this :)

The modem generally can't detect that some (human) has answered the line, but
it should time out eventually with a "NO ANSWER". (If you hit
space/enter/etc. the modem should drop the line and report "NO ANSWER" or
somesuch as well...)

One of the "S" registers defined how long the timeout is, although most
terminal software with built-in dialing functionality had their own timeouts
since the defaults for many modems were rather long (e.g., 30-60 seconds).

How long did you wait?

What modem are you using?

--Joel
A good ol' Motorola 9600 external was great for making it dial. I used
it to speed dial radio stations during contests..

That's correct -- modems don't detect ringing on the destination line.
They do, however, immediately detect a busy, which can be considered
just as conclusive for the next step.

Maybe you posted it before and i missed it. Just what is the exact
make model and revision of each modem you have tried. Where does a
non-owner get the command set references for each make, model and
revision of modem you have tried? What specialized software does each
modem come with? Where do you find any file format specifications
needed? Throw us some bones here.

I have used a number of differnt modems since the late 80's or
whenever Hayes came out with their 1200 baud modem.
Their command set was copied with little variation by others tht saw
the popularity (and sales) of the Hayes modem.
You cannot be far astray on using that command set, which should
still be available on the web.

Yes and no. I found 4 different series of voice modem command sets.
They are not interchangeable.
