NCR USB DynaKey Control Data Capture Registry Values
NCR Data Capture Registry values appear under the registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\NCR\NCRUsbKeyboardCtl\DataCapture] "DcapControl"="10 (Hex destination(s): 1=DCap App, 2=Debugger, 4=File; 10/20/40 for immediate)"
"DcapFile"="C:\\NcrDataCap.log" "DcapFileMax"="0 (Max KB of data cap file)" "DcapMask"="00000003 (Hex mask of events to capture)" "DcapTime"="1F00 (Hex time option(s): 100=m:s, 300=h:m:s, 700=m/d h:m:s; 800+digits=millisec; 1000=threadid)" "DcapVersion"="1.1.3" "DcapLinePrefix"="NCRUsbKeyboardCtl "
Set DcapMask to 0x01 to receive only Error messages. Set to 0x02 or higher receives all messages.
Set USB Key Matrix Application
SetUsbKeyMatrix is a Windows application for the Desktop O/S versions (Windows 98se, Windows 2000) that uses the NCRUsbKeyboardCtl control to set a keyboard matrix map. The application operates as a memory-resident background process for a duration that may be specified on the command line. If no duration is specified, the application remains resident until terminated by user action. While resident, the application receives device-attachment notifications for HID devices, and when these are received, invokes the NCRUsbKeyboardCtl control to set the keyboard matrix map.
Command-line parameters may include a value for the runtime duration. If specified, the application remains resident only for the requested duration. This permits the application to be used only during defined events such as system start-up, and after which the application will no longer remain resident in memory. The command- line parameters may also specify that a background memory-resident instance of the application should be terminated. In this case, the application only terminates the background instance, and does not remain resident itself or invoke the control to set the keyboard matrix map.
