Automatic Uplink Power Control (AUPC) Commands / Queries

The instruction codes that follow are valid only when the SLM-5650C 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.
