has changed, or on polling after +WANTST has been received regardless of whether the state has changed
or not. An initial state of ‘stowed’ can be assumed, but +ANTST:<ant status> will be sent shortly after
initialization with the actual status in any case. Internal polling will measure the deployment and docking
detector states before any overall state change is announced.
Note that internal polling occurs on each main receiver receive activity, i.e. once per 90ms during a call, at
least once every 4.3 seconds while monitoring a Ring signal, and as infrequent as once every 2 minutes
when performing Ring searches with no signal present.
The +WANTST command and +ANTST notification are used internally to the 9555 Handset, and are not
intended for use by end users. The +WANTST command is not available on the 9522B LBT (so the
ANTST notification will never be issued).

This message is used internally to the 9555 Handset, and is not intended for use by end users. This
notification is not available on the 9522B LBT.
