Events - Serial COM
WDterm
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. The
only event that does not pass any data is
OnTermBaseRegister
. All others
pass at least the Terminal ID on which the event occurred.
OnTermData
also passes the data that was keyed or scanned into the terminal.
Terminal ID is always passed as 0-63. A Terminal ID value of 99 indicates
an error.
Once you have the event handler skeletons, you can proceed to add
whatever functionality you desire to each event.
You must call the
OpenDevice
method before any events can be fired.
OnTermBaseRegister
Event:
An attached base station has successfully powered
up and communicated with the host computer via
the serial connection.
