AT Commands
When utilizing the USB data communication port, the DriveDOCK Extreme
cannot activate AT commands that could interrupt the docking station's
synchronization with the Extreme handset. Therefore, the DriveDOCK
Extreme will block or limit AT commands that could cause any adverse
effects to the functional operation of the cradle. Please refer to the Iridium
"ISU AT Command Reference" document for more details on the AT
commands supported by Iridium.
