In addition to the Wa, Te, and Tr commands, SAMSys readers also support the
following EPC1 operations:
Lb Lock Block
Yl Query Lock Status (returns f:0 for unlocked or f:1 for locked)
Td Tag Destroy
The Lock Block and Query Lock Status operations can only be performed with a
single tag in the RF field and do not require any parameters. The Tag Destroy
operation requires the b: parameter to specify the particular kill passcode for this
tag.
For detailed information on these and other tag commands, refer to the
Comprehensive Heuristic Unified Messaging Protocol (CHUMP) Reference
Guide.
