AT Modem command for steady tone

By runningwolf ·
I have need for an internal modem in a Toshiba 4060CDT laptop to generate a steady tone after dialing the number, so that the device (not a computer modem) on the other end will know to pick up the line after the client auto-attendant software has picked up. This works for me on a hayes Optima 24 external on a desktop, but I have tried the exact same string and I don't get the tone. I don't know what makes the hayes do it.

AT Modem command for steady tone

I can't tell you what to do to make it work but I know why it might not work, some internal laptop modems are sort of "oddballs" they don't allways follow the hayes standards for commands. thus they can be a real pain to set up.

these commandscould come in handy:

ATI3 and ATI4 -information commands, often returning the modem's manufacturer and model.

The commands that make a modem do this work by putting the modem in 'Answer' mode as opposed to the default 'Originate' mode when you use a dial string.

I wouldn't think that these commands would have changed either: as they are historically 'standard set' commands.

The problem is probably other commands in the string which are recognised by the Hayes but not the one in your laptop.

If you don't know the identity of your modem try sending the commands singularly to check for an 'OK' after each.
