Loading and saving trace data:

Data that you have captured can be saved to the hard
disk (drive C:), or to a floppy diskette (drive A:).
You may save either all the frames or only those frames
which pass the display filters and are visible in the
summary view. 

Saved filtered data may be reloaded and futher filtered
with different options, which is a technique useful for
creating complex display filters.

Saving and retrieving setups:

A "setup" is the complete collection of options you
have chosen for the Sniffer, including all the menu
selections, choices of patterns, protocol levels, etc.
The current setup can be saved in a named file and and
can be subsequently reloaded.

Symbolic station names are saved separately, as
described in "Managing symbolic names".

How to indicate which is to be saved or loaded:

Under the "save" and "load" menus you can select
whether setups or frame data is to be transferred.
The default is frame data, and you can press ENTER on
the "save" or "load" item for that choice.

To save or load setups, select the "setup" menu item
and press ENTER.

Selecting the range of frames to be saved:

You can save any range of consecutive frames.  You may
specify that you wish to start or end at the first or
last frames, or use the "From nnnn" and "To nnnn"
options to specify a more restrictive range.  The
default frame numbers supplied are those of the marked
frame and the currently highlighted frame, but they may
be changed by pressing ENTER when those menu items are
chosen.

Selecting a subset of frames to be saved:

By checking the option "Filtered only", just those
frames which pass the current display filters will be
saved.  The summary window is a good place to verify
that the frames which pass the filters are the ones
you intend to save.

The station address filter, protocol filters, and
pattern match filters will all affect the selection.

Where information is saved:

When you save data or setups, you supply a one to eight
character alphabetic name.  The Sniffer adds a three
character suffix appropriate for the file type, so you
may use the same name for related setup and data files
if you wish.

The screen window will prompt you with the disk name
and subdirectory for the proposed file. If you wish to
change it you can erase part or all by backspacing and
typing in different values, or you can simply add the
filename to the proposed directory.

Where information is loaded from:

You may load data and setups from a file in any
subdirectory.  Only files with the appropriate
extension for the object you are loading are displayed.
You choose a file by moving the highlight bar to it and
pressing ENTER.

See "Moving around in the DOS file directory" for more
information about changing directories.
