List of AT Commands for Nokia 22

Description
This command allows the controlling of the Call Waiting supplementary service. Activation,
deactivation and status query are supported. When querying the status of a network service
(<mode>=2), the response line for ‘not active’ case (<status>=0) should be returned only if the
service is not active for any <class>. The parameter <n> is used to disable/enable the presentation
of an unsolicited result code +CCWA: <number>,<type>,<class>[,<alpha>] to the TE when a call
waiting service is enabled. The command should be abortable when the network is interrogated.
The interaction of this command with other commands based on other GSM supplementary
services is described in the GSM standard.
The test command returns the values supported by the TA as a compound value.
