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, using a communications pro-
gram such as Windows HyperTerminal.
