World Wide Web at www.modems.com. Click Technical Reference Infobase and then AT Command Sets under Communications and Software Issues.
If your software suggests an initialization string for this modem, you should use it. If your software does not list this modem and no initialization string is suggested, use the following: AT &F.
Your telephone service may include Call Waiting that you can temporarily suspend by using your phone to dial a special code. (For example, in the U.S., you can disable call waiting by adding *70 to your dialing prefix; please check with your local phone company for the correct code for your area.) You can include that code, followed by a comma, in the dial string or dial prefix in your software.
If your software does not handle AT commands automatically, it should provide a place to enter AT commands in its setup menus. However, in some cases you may need to enter AT commands directly to the modem. You must do so from a data program’s terminal mode.
Using Terminal Mode to Enter AT Commands
Start your data communications program.
Change to terminal mode (also called command, local, direct, or dumb mode). Check your software documentation for additional instructions.
Type AT plus the command you need and press Enter. You will see an OK response.
When you finish, you can return to the data communications program’s standard user interface. See the software program’s documentation if you need help.
To return to the factory default settings for the modem, in terminal mode, type AT &F and press Enter.
Refer to the Troubleshooting section for more tips about AT commands.
