The analyzer provides a way for you to supply the context for any frame, provided the decoder supports it.
(The decoder writer has to include support for this feature in the decoder, so not all decoders support it.
Note that not all decoders require this feature.)
If the decoder supports user-provided context, three items are active on the
Options
menu of the
Control
window and the
Frame Display
window. These items are
Set Initial Decoder Parameters
,
Automatically Request Missing Decoding Information
, and
Set Subsequent Decoder Parameters
.
(These items are not present if no decoder is loaded that supports this feature.)
Set Initial Decoder Parameters
is used to provide required information to decoders that is not context
dependent but instead tends to be system options for the protocol.
Choose
Set Initial Decoder Parameters
in order to provide initial context to the analyzer for a decoder. A
dialog appears that shows the data for which you can provide information.
If you need to change this information for a particular frame :
1. Right-click on the frame in the Frame Display window
2. Choose Provide <context name>.
Alternatively, you can choose
Set Subsequent Decoder Parameter
from the
Options
menu.
3. This option brings up a dialog showing all the places where context data was overridden.
4. If you know that information is missing, you can't provide it, and you don't want to see dialogs asking
for it, un-check
Automatically Request Missing Decoding Information.
5. When unchecked, the analyzer doesn't bother you with dialogs asking for frame information that you
don't have. In this situation, the analyzer decodes each frame until it cannot go further and then simply
stop decoding.
