[Sample of status reply ]
When [DC2]PK is received using a tag with 04123456789ABC of UID.
■Write successful (UID read successful)
[STX]23,1,N,UD:04123456789ABC[CR][LF][ETX]
■Write successful(UID read fail)
[STX]9,1,D,UD:[CR][LF][ETX]
■Write fail (UID read failed)
[STX]9,0,D,UD:[CR][LF][ETX]
[Supplemental explanation]
1.The write status and UID is returned when [DC2]PK is received after RFID write.
2.Although write is successful status will be returned without data if you fail to read UID since UID read will be
done separately from write.
3.Return data remains the same when code write is specified without print data. Previous value will be returned.
