C.6.6 Automatic Uplink Power Control (AUPC) Commands / Queries
The instruction codes that follow are valid only when the SLM-5650A Satellite Modem type has been set to AUPC.
Note: 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.
