The :NORDer command is used to send an order type mobile station control message
to the mobile station. The Access annunciator will light momentarily while the Test
Set is sending the mobile station control message.
A mobile station must be actively connected on a voice channel to the Test Set (that is,
the Connect annunciator lit) before attempting to send an order to a mobile station.
The query form of the command (that is, :NORDer?) can be used to determine the last
order sent to the mobile station using the :NORDer command.
