External computer modemIt is important to note that there are some computer modems that do not contain a speaker and therefore will not emit sound if enabled or disabled. Additionally, the modem speaker may become defective, and therefore will not be able to emit sound.

The following steps describe how to enable or disable the computer's internal, not external, modem speaker. Some computers may have the capability of emitting the sound through the computer speakers and following the steps below may not enable or disable this as other software may be involved.

Windows 95 and above users

To adjust the modem speaker follow the steps below:

  1. Open Control Panel - Click Start, Settings, Control Panel
  2. Open Modems - Double-click the modems icon
  3. Highlight the modem that you want to adjust the volume and click the "Properties" button. (Note: do not click "Dialing properties." Instead, click the "Properties" button.)
  4. This window provides an interface for adjusting the volume. Moving the volume slider all the way to the left will reduce the volume to silent, and moving it all the way to the right will set the volume to maximum.

DOS and Windows 3.x users

The above AT commands can be typed at an MS-DOS prompt or through the terminal or dialing program. It is important to note that not all modems support the above commands.
