Capturing a Data DWORD
InFusion provides the ability to capture individual data DWORDs and provides four
different registers to store captured DWORDs (DWORD #0, #1, #2 and #3).
To capture a data dword, select Capture Data DWORD from the Action Properties screen,
as shown below. Select the register to be used to store the DWORD from the drop ‐ down
menu under the Capture Register property.
Figure 4.19: Capture Data DWORD Action
Using Captured Data DWORDs
Captured data DWORDs can be used in creating events for data that match the captured
DWORD(s), or in creating actions to substitute the captured DWORD(s) into the data
stream.
To create an event using the captured DWORD, in the Event Properties menu, select SAS
Data Pattern (or SATA Data Pattern ), and then select any of the 12 DWORDs ( DWORD 0
Type through DWORD 11 Type ). The drop ‐ down menu provides the choice of a custom
DWORD or any of the four captured DWORDs. If you select a captured DWORD, the Value
field beneath this selection is hidden (the Value field is only used for specifying custom
DWORDs). Note that choice of a mask and an offset are still available when using
captured DWORDs.
