Modem genius wanted

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?

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.

That's correct -- modems don't detect ringing on the destination line.

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 These are "connection progress" messages I should be getting from the

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 :)

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

They do, however, immediately detect a busy, which can be considered just as conclusive for the next step.

I thought most modems had a verbose VS silent mode...

That's my understanding as well. Most modems have configuration registers into with which you can control modem behavior, including the kinds and number of progress messages.

Unlike the basic AT command set, many of these are modem specific, so the documentation for that particular model must be consulted.

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.

sounds like you are not waiting long enough
