'P' (Download all stored barcode)

Parameters: None.
Format: 'P'
Output: A multi-byte string (see below)
Purpose: Get all barcodes data stored in KDC100 internal flash memory. 'P' command does not
erase the stored barcodes.
[Note] The format of the output is as follows:
N C Y D T
0 0 0 0
Where
N : Total number of bytes to be sent(3 bytes)
C0, C1,..., Cn : Total number of each barcode data(1 byte) including Y/D/T bytes (not including C byte)
Y0,Y1,..., Yn : Type of each barcode(1 byte)
−
Bit 0 ~4 : Barcode type

−
Bit 5 : 1 if matching slave data, 0 if mismatching slave data
−
Bit 6 : 1 if master data, 0 if slave data
−
Bit 7 : 1 if data is collected in Master/Slave Application, 0 if data is collected in Normal mode
D0,D1,...,Dn : Actual barcode data of each barcode(variable size)
T0, T1,...,Tn : Timestamp of each barcode(4 bytes)
The first 3 bytes specify the total number of bytes being sent. Then the entire populated
contents of the internal flash memory are sent as is.
