IMPORTANT:
When you power ON or reset the Courier, the
DIP switch settings override the settings you may have made
previously using AT commands.
If you change the DIP switch settings while the Courier is
powered ON, you can avoid powering the Courier off to make
the new settings take effect. Just send the Courier the ATZ
command.
