SLM-5650 Satellite Modem
Remote Control
Automatic Uplink Power Control (AUPC) Remote Control Commands.
The following commands are only valid when the SLM-5650 modem type has been set to AUPC. Note: Always wait 3 seconds between
consecutive remote modem command/query polls. If Local AUPC is not enabled, query commands 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.
