associated SignIn event and a given terminal should not be allowed to SignIn twice without an

Concepts
When you use drop-in components in your program you will follow the standard object-oriented programming
paradigm that uses properties, methods, and events to implement the functionality of the drop-in component.
Properties are the various configuration variables used by the drop-in component. An example of a
•
property is the ComDeviceName setting.
Methods are function calls used to issue commands and access features of the drop-in component. An
•
example of a method is sending an Input command to the terminal.
Events are function definitions placed in your application's source code. The function definitions in your
•
source code are called Event Handlers. The skeleton structure of the event handler's source code is
automatically generated. The code in the Event Handler is called ("fired") by the drop-in component
when a specific event occurs. An example of an event is when a terminal returns data and the
OnTermData event is fired.
The details of how to access Properties/Methods/Events varies between development platforms. Details of how it
works in some of the most popular platforms is illustrated in the samples included with the RF Utilities CD or
available for download from our website at:
Properties
Properties are the various configuration variables used by the WDterm control. They are directly assignable in your
application (e.g. "WDterm.ActiveTerminal = 5") and can be set in your development environment's object
browser.
Important: Except for ActiveTerminal and Quiet, all properties require the serial port to be "closed" before they
can be changed. Use the CloseDevice method before setting properties and then call OpenDevice to re-open the
serial port.
Note that your development environment may show more properties for the WDterm control than are listed here.
This is normal. You may ignore properties you see that are not listed here.
ActiveTerminal
Valid values: 0 through 63.
Definition: This is the terminal ID (0-63) to which method call instructions are directed .
1. A terminal going out of range and having its power cycled before returning within range
OR
2. Two (or more) terminals using the same ID (terminal ID conflict).
