J
Requests the Reader to restore settings to factory defaults (no data).
(The Reader will respond with d or e.)
L
Requests the Reader to send a list of its stored files; data is either empty or contains “1”;
hidden files are listed only if “1” is specified. (Hidden files are files whose names begin
with a period.)
(The Reader will respond in the same manner as with the ‘(’ command, each z packet
containing a file name as a NUL-terminated string of printable ASCII characters.)
Note: Supported in firmware version 3100+
N
Requests the Reader to delete stored data and images (no data).
(The Reader will respond with d or e.)
O
Set a bit (or bits) in a Reader setting; data is as defined in the / command; the specified
integer is ORed with the existing setting value.
(The Reader will respond with d or e.)
Note: see Section 8 for possible Reader settings.
P
Put setting to Reader; data is as defined in the / command; the specified integer replaces
the existing setting value.
(The Reader will respond with d or e.)
Example – enable Rectangular Data Matrix (setting 0x16, value 1): P%161
Note: see Section 8 for possible Reader settings.
Q
Clear a bit (or bits) in a Reader setting; data is as defined in the / command; the ones-
complement of the specified integer is ANDed with the existing setting value.
(The Reader will respond with d or e.)
Note: see Section 8 for possible Reader settings.
R
Requests that the previously sent packet be re-sent by the Reader; data may specify a
maximum packet size the receiver will accept: data is either empty or specifies a 16-bit
big-endian unsigned integer (2 bytes). If data is empty or specifies a size less than 32 (the
minimum packet size), the Reader will use its preferred maximum packet size.
Otherwise, it will use the specified max packet size (or less) and will fragment data
across multiple smaller packets when necessary.
(The Reader will respond by resending its previous packet or with e if there was no
previous packet. If the max data size has changed, it may resend the previous data in a
sequence of more than one packet.)
