T
Requests the current date and time (no data)
(The Reader will respond with d with data containing the date and time formatted as
yyyy-mm-dd hh:mm:ss.)
Note: on units without a battery-backed real-time clock, the date and time will reset to
2000-01-01 00:00:00 upon power-up.
Supported in firmware version 2526+
U
Requests the Reader to delete all stored files including data, images, and JavaScript files
(no data)
(The Reader will respond with d or e.)
Supported in firmware version 2526+
W
Requests the Reader to write its current settings from RAM to its non-volatile memory.
(The Reader will respond with d or e.)
X
Initiates data transfer from Reader memory to Host; data specifies whether only buffer
data or all data (buffer and log) should be sent: if empty, all data are sent; otherwise, 0
requests only buffer data and 1 requests all data (buffer and log).
Note: if the autoLogErase setting is nonzero, the log data are cleared after being
successfully sent.
(The Reader will respond with a g packet, zero or more z or p packets, and a final d or e.
In raw mode, the g and d or e packets are omitted; thus if there are no data stored then no
response will arrive.)
Y
Acknowledge the receipt of a packet; data specifies the received packet number (one
byte).
(The Reader will not respond.)
Z
Request the Reader to reboot; data is either empty or contains ‘1’; if it contains 1, the
Reader will reboot into boot loader mode.
(The Reader will respond with d or e before it reboots.)
Enhanced to include the Z1 feature in firmware version 2526+
\
Returns a string previously stored with the B command; data contains the event number
of the stored-command-code as a single byte.
(The Reader will respond with a d packet containing the requested null-terminated string
or with e (e.g., if the specified event number is out-of-range).)
See “Appendix: B-string Settings” for complete details.
