Note: in the query command the class parameter must not be issued.

Note: the difference between call waiting report disabling (AT+CCWA =
0,1,7) and call waiting service disabling (AT+CCWA = 0,0,7) is that in the
first case the call waiting indication is sent to the device by network but this
last one does not report it to the DTE; instead in the second case the call
waiting indication is not generated by the network. Hence the device
results busy to the third party in the 2

case while in the 1

case a ringing

indication is sent to the third party.

Note: The command AT+CCWA=1,0 has no effect a non sense and must
not be issued..
