<STATUSs>
If the TARGETID is unknown, a communication error (CE) occurs.
Exceptions:
 For single-page TIRIS transponders, only 8 bytes are written.
 If this command fails, some or all of the previous data in the
transponder might be lost. Read the transponder to confirm the
contents of the transponder.
 If the TargetID is invalid, no statuses are sent (list of zero).
ATTENTION
The reader must be in the maintenance mode to write the MID with
message S18F11.
ATTENTION
If the length of the MID is longer than what the subsystem can accept,
the subsystem will return a failure message in the reply SSACK. If the
length of the MID is less than the maximum allowed length of device,
then the MID will be padded with “0” in the front. Refer to MicroTag
