Get Multiple Block Security Status
When receiving the Get Multiple Block Security Status command, the LRI2K sends back the
block security status. The blocks are numbered from '00 to '3F' in the request and the value
is minus one (–1) in the field. For example, a value of '06' in the "Number of blocks" field
requests to return the security status of 7 Blocks.
