The = command is most useful to ‘pre-set’ a new communication mode that will become active after a
reboot.
(The Reader will respond with d or e.)
Note: Also see commands O, P, Q, /, =, W. See Section 9 for possible Reader settings.
>
Causes the Reader to send a string of text to the Host as a z packet;
data contains the text to send.
(The Reader will respond with a z packet containing the text.)
@
Causes the Reader to reset its internal date/timestamp to the specified time; data contains the date
and/or time in one of the following formats.
yyyy-mm-dd hh:mm:ss
yyyy-mm-dd hh:mm
hh:mm:ss
hh:mm
Note: the separators are optional; only digits are significant.
(The Reader will respond with d or e.)
Examples:
Set to midnight:
@00:00
Set to Sept 1, 2005 11:52:02 PM:
@2005-09-01 23:52:02
A
Notifies the Reader that the previously sent data were rejected for one of the following reasons:
The packet was encrypted and the decryption failed.
The Host (CodeXML
®
Modem) is locked to a different Reader.
The Reader should indicate to the user that the packet has been rejected; e.g., it may sound error
beeps. See related register 12F: notify-of-packet-rejection.
(The Reader will not respond to the Host.)
C
Apply a value to a register on the reader and save the value; data is in one of the following formats:
C(XXX)YYY where XXX is the register number and YYY is the setting value, both in ASCII hex. This will
change the value in the register and save it. For example C(26)64 will change the value of register 26
to 0x64 and save this setting.
C/(XXX)YYY where XXX is the register number and YYY is the setting value, both in ASCII hex. This will
toggle the bits in YYY and then save the resulting value (see / command). For example C/(1F7)40 will
toggle bit 6 of register 1F7 and save this setting.
CO(XXX)YYY where XXX is the register number and YYY is the setting value, both in ASCII hex. This will
set the bits in YYY (change those bits to 1s) for register XXX (see O command). For example CO(1F7)40
will set bit 6 of register 1F7 high and save this setting.
CQ(XXX)YYY where XXX is the register number and YYY is the setting value, both in ASCII hex. This will
clear the bits in YYY (change those bits to 0s) for register XXX (see Q command). For example
CQ(1F7)40 will clear bit 6 of register 1F7 and save this setting.
