complete picture of the Host screen. The more checkpoints you have within a recording,
the quicker it is to locate a particular point within the recording. However, adding too
many checkpoints can drastically increase network traffic and cause the recording files to
become very large.
 To set the Automatic Checkpoint Generation, type a value for the following settings:
 The Minimum data size (KB) before criteria checked field specifies how much
screen data must be generated in a recording before the PC-Duo Gateway will
begin to check the other two Automatic Checkpoint criteria.
 The Maximum data size (KB) after minimum field specifies the largest amount of
data than can be recorded before the next checkpoint must be generated.
 The Maximum duration (seconds) after minimum field specifies the longest
amount of time that a recording can go before the next checkpoint must be
generated.
 To set the Limits for a recorded session, type a value for the following settings:
 The Maximum recorded session size (KB) field specifies the largest file size for
a recording.
 The Maximum recorded session duration (hours) field specifies the longest
amount of time that a recording can last.
 The Automatically delete sessions older than (hours) field specifies how old a
recording can be before it is deleted. Recordings which exceed this limit are
deleted according to the schedule you specify in the Schedule tab.
 To set Screen Capture Preferences, choose one of the following settings:
 By default, the Gateway will defer to the screen capture preferences selected
by the Host, so the option Use Host settings for screen capture preferences will be
set (see Screen tab in PC-Duo Host Guide for more information).
 If you prefer to override the Host preferences, select Override Host settings as
follows: and choose one of the following two options:
- Prefer kernel mode, but use this profile for user mode will attempt to use
kernel mode drivers to capture screen data on Host, as long as kernel
mode drivers are available (generally the case for Windows XP, Windows
Server 2003 and older platforms)
- Prefer user mode, and use this profile will use user mode code to capture
screen data on Host and will use the bandwidth throttling settings according
to the "user mode profile" that can be accessed by pressing Configure...
The description for the currently selected user mode profile will appear as a
text field next to the Configure... button (for example, "High Quality/High
Bandwidth").
Bandwidth throttling
The user-mode screen capture technology has the ability to "throttle" itself to a restricted
amount of bandwidth. This may be preferable when responsiveness and throughput are
more important than screen quality, particularly over low-bandwidth connections.
The amount of throttling is controlled by parameters set in a "user mode profile". The
“Configure…” button on the Screen tab brings up a dialog that allows the end-user to
select a hard-coded, predefined configuration, or to specify a custom configuration.
