deactivation and status query are supported. Parameter <n> is used to disable/enable
the presentation of the unsolicited result code to the DTE when the Call Waiting
service is enabled.
Command is abortable in the cases 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.
Defined values
<n> (sets/shows the result code presentation status in the A3LA-RG):
0 disable unsolicited result presentation
1 enable unsolicited result presentation
On a DTE-DCE command, <n> will set the result code presentation status in the
A3LA-RG, regardless of the value of any <mode> parameter.
<mode> (when <mode> parameter is not given, network is not interrogated):
0 disable Call Waiting service for specified class(es)
1 enable Call Waiting service for specified class(es)
2 query status of Call Waiting service for specified class(es)
<classx> is a sum of integers each representing a class of information:
1 voice
2 data
4 fax
This parameter defaults to 7, equal to all classes, but the A3LA-R/RM/RGS only
supports Voice Call Waiting so this is illegal. Therefore in practice the DTE must
supply <classx>=1.
<status>:
0 Call Waiting service not active for specified Class
1 Call Waiting service active for specified Class
<number>: quoted string type phone number of calling address in format specified by
<type>
