10.3.7 Automatic Uplink Power Control (AUPC) Commands and Queries
The instruction codes that follow are valid only when the SLM-5650A Satellite Modem Type has been set to AUPC.
Always wait three (3) seconds between consecutive remote modem command/query polls. If Local AUPC is not
enabled, queries will return the last known condition. A request for status from the remote modem will then be
transmitted, ensuring that the next query will return current status.
