SA — Sequential Acknowledge
Enables or disables sequential acknowledgment mode. When enabled, the device requires an ACK response from the server for each event report before sending the next one.

Notes
- When enabled, the device appends a sequence ID (
;SI=NNN) to outgoing reports. - The server must reply with the same sequence ID to acknowledge receipt.
- Unacknowledged reports are queued and retried.
