This command controls the Call Waiting supplementary service, including the settings and the 
queries of the G24-L and the network. When the Call Waiting indication is enabled by the G24-L 
and there is a waiting call, a +CCWA: indication is sent from the G24-L to the terminal.

The G24-L supports only one of the services at a time: Voice, Data or Fax. Multiparty is 
a voice-only functionality.

A CCWA indication is sent to the terminal only during a voice call-waiting event. A
CCWA indication is not sent for a fax/data call during in a voice session.

When a call-waiting indication is enabled by the G24-L (<n>=1), the following unsolicited 
indication is sent to the terminal from the G24-L:

The Set command enables/disables the 
Call-Waiting indication in the G24-L and 
in the network. Activation, deactivation 
and status query are supported.

When the <mode> parameter is set 
to 2 (network query), the <n> 
parameter is ignored. This means 
that no enable/disable action is 
performed while querying the 
network.

The Read command returns the 
enable/disable status of the call waiting 
indication in the G24-L (<n>).

The Test command returns <n> values 
supported by the G24-L as a compound 
value.
