Disable Last In First Out (LIFO)

By default, the last client to send a command packet will get all future telemetry responses. If disable

LIFO field is set to 1, the client must add themselves to response list via Set Packet Destination (0x64) .

For example, Client A sends commands to the SLA-HARDWARE for configuring stabilization and Set

Coordinate Reporting Mode (0x0B) frequency to 10 Hertz. Client A then gets all the Tracking Position

(0x43) responses as expected. Client B sends a Get Version (0x00) command to the SLA-Hardware.

Client B receives the Version Number (0x40) response as expected, but then begins getting all of the

tracking position responses. Client A will no get NO tracking position responses, since Client B was

the “Last In”.

If Client A had set the DISABLE LIFO bit to 1 and then added itself to the Packet Destination list,

Client A would continue to get tracking position responses from the SLA-HARDWARE even if Client

B sends it commands.
