The Distinct VT220 ActiveX control allows you to integrate VT220 emulation and optional login capabilities into your applications. It has built-in Telnet capabilities to connect to the
remote server. An application with VT220 emulation allows users to remotely access applications that require a VT220 terminal. This ActiveX control supports full VT52, VT100 and VT220 emulation and
includes extensive keyboard mapping capabilities. This ActiveX control takes care of establishing the TCP connection, handling option negotiations, sending user input to the server and displaying
incoming data in a VT220 emulation window. As an option, the application can handle establishing a connection and sending and receiving data itself. This allows the application to use a transport
protocol other than TCP/IP (such as a direct modem dialup).
The combined use of the Distinct VT220 control and the Distinct Windows Sockets control allow you to do data manipulation. An example of when you may need this is an application that reads a file
containing customer account data that needs to be entered into an existing billing system's user interface. The application needs to process the file data and, through VT220 emulation, enter it
through the user interface. We provide a sample with source to illustrate the combined use of the VT200 and Windows Sockets controls. This sample is available for the C++ and Visual Basic
environments.
The main features of this control include the ability to:
· create and manage multiple configuration profiles each with their own settings.
· select the standard deck fonts or a custom font.
· remap the keyboard. A full keyboard remapping capability with a built in pre-programmed graphical representation of the keyboard to facilitate the remapping of keys
in your application.
· capture all incoming data to file.
· capture screen data to a file.
· manipulate incoming data (when used in conjunction with the Windows Sockets control)
· cut and paste data from and to the emulation window via the Windows clipboard.
