Overview

The Telnet protocol is used to establish a connection with a server which provides a virtual terminal session for a user. Its functionality is similar to how character based consoles and serial terminals work, enabling a user to login to the server, execute commands and interact with applications running on the server. The control provides an interface for establishing the connection, negotiating certain options (such as whether characters will be echoed back to the client) and handling the standard I/O functions needed by the program.

The control also provides methods that enable a program to easily scan the data stream for specific sequences of characters, making it very simple to write light-weight client interfaces to applications running on the server. This control can be combined with the SocketTools Terminal control to provide complete terminal emulation services for a standard ANSI or DEC-VT220 terminal.

This control supports secure connections using the standard SSL and TLS protocols. To establish a secure connection to the server using the Secure Shell (SSH) protocol, use the SocketTools SshClient control.

Requirements

The SocketTools ActiveX Edition components are self-registering controls compatible with any programming language that supports COM (Component Object Model) and the ActiveX control specification. If you are using Visual Basic 6.0 you must have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools.

This control is supported on Windows 7, Windows Server 2008 R2 and later versions of the desktop and server platforms. If you are using Windows 7, you must have Service Pack 1 (SP1) installed as a minimum requirement. It is recommended that you install the current service pack and all critical updates available for the operating system.

This product includes both 32-bit and 64-bit ActiveX controls. Native 64-bit CPU support requires the latest 64-bit version of Windows 7, Windows Server 2008 R2 or later versions of the Windows operating system.

Distribution

When you distribute an application that uses this control, you can either install the file in the same folder as your application executable or as a shared component in the appropriate system folder. If you install the control in the system folder, it is important that you distribute the correct version for the target platform and it must be registered. If you install the control in the same folder as your executable, it is recommended that you use registration-free activation or COM redirection to ensure that the correct version of the control is loaded by the application.
