Page 2 : User Interface Confi guration 1 of 2
The “Enable Built-in Link Watchdog UI” specifi es
whether or not the Link Watchdog user interface
program is allowed to run. If enabled, it is launched
automatically by the LWD service when the service
determines the link is down. This is to inform the user
of the device what is happening. It is critical for totally
online applications such as terminal emulation and
Internet Explorer. If the user attempts to use a browser
based application without a working network link some
form of connection error page will be shown. End users
typically do not know how to behave in this situation.
The LinkWatchdog User Interface component locks the
device down, so that it cannot be used while the link is
re-established. The UI component also displays status
information to the user. The only case where the UI
component would be undesirable is if your application
is tailor-made to communicate directly with the LWD
service, thereby rendering the default user interface
component unnecessary and disruptive.
