Events – WD802Term ActiveX
WD802term events occur when a specific condition is met. When an event
is "fired", an event handler function in your application is called.
Though the details of exactly how it is done varies from one programming
environment to the next, the source code skeletons for the various event
handlers are automatically generated and inserted into your source code for
you. See the samples for more specific information.
Each event passes relevant information to your event handler function. For
example,
OnTermData passes the data that was keyed or scanned into the
terminal.
Terminal ID is always passed as 0-999.
Once you have the event handler skeletons, you can proceed to add
whatever functionality you desire to each event.

Server on by calling
WD802Term.InitializeServer
WD802Term.ServerActive = True
