+PCW Command

This command configures how the modem responds to a call waiting signal. The modem’s response is also determined by the current configuration of the +VCID caller ID command (See “+VCID Command” on page 79 for information on this command). You can also use the +PCW command to display the current call waiting configuration, and to display the supported <call waiting> parameter values.

+PCW=<call waiting>

Valid <call waiting> parameter values are as follows:

0Enables the call waiting detector. When a call waiting signal is detected, the modem responds to it according to the +VCID caller ID command configuration. This is the default.

2Disables the call waiting detector.
