Track Data Send Flags Property (KB, BulleT SPP, Bullet KB, UART, RS-232)
Property ID: 0x14
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0x63 for all models except BulleT KB which defaults to 0x6B
Description: This property is defined as follows:
ICL SS ES LRC MKR LC Er Er
ICL 0 – Changing the state of the caps lock key will not affect the case of the data
1 – Changing the state of the caps lock key will affect the case of the data
SS 0 – Don’t send Start Sentinel for each track
1 – Send Start Sentinel for each track
ES 0 – Don’t send End Sentinel for each track
1 – Send End Sentinel for each track
LRC 0 – Don’t send LRC for each track
1 – Send LRC for each track
Note that the LRC is the unmodified LRC from the track data. To verify the LRC
the track data needs to be converted back from ASCII to card data format and the
start sentinels that were modified to indicate the card encode type need to be
converted back to their original values.
Note that this property only applies to track data sent via the keyboard interface
and completely in the clear (Security Level 2).
MKR 0 – Don’t minimize key reports
1 – Minimize key reports
This flag is currently only supported for the BulleT KB interface. It should be set
to zero for all other interfaces. Support fot this flag may eventually be added for
the USB KB interface.
When not minimizing key reports, the maximum number of key reports is sent to
represent each character. When the ASCII-to-keypress conversion type property
is set to ACTIVE KEYMAP, this consists of two key reports per character (one
for the key down and one for the key up). When the ASCII-to-keypress
conversion type property is set to ALT ASCII code, this consists of eight key
reports per character (Alt down, first digit down, first digit up, second digit down,
second digit up, third digit down, third digit up, Alt up). This mode is slower but
it will work with all applications.
