PowerTCP Telnet for .NET allows you to communicate with servers using Telnet, rsh, rlogin, or rexec. Designed for beginners and advanced developers with automated scripting and direct access to the data stream. Manages Telnet, rsh, rexec, and rlogin server sessions with fewer required lines of code, but greater flexibility. Ideal for .NET desktop and ASP.NET applications.
Updates in V4.4
- Some custom Start delegates have been replaced with the .NET Framework standard WaitCallback delegate. This generally means that callback functions no longer include the calling component as a parameter (this is true even for custom delegates that were not replaced).
- The Connect method was updated to take the new TcpSession object as a parameter. TcpSession is a serializable object that facilitates the saving of session settings.
- The AuthenticateAsClient and AuthenticateAsServer methods were updated to take the new ClientSecurity and ServerSecurity objects as parameters, respectively. These two objects are serializable, facilitating the saving of security sessions.
- The ReadToX functions (ReadtoDelimiter, ReadToCount, ReadToEnd) were updated to throw the new DataException when an error condition occurs. DataException includes a DataRead field which provides the data read prior to the exception.
- Several samples were updated with "model" classes, to fall more in line with the Model-View-Controller (MVC) design philosophy. For more on MVC, see the "MVC Design in Applications" page of the help file.
About Dart Communications
Dart Communications was founded in 1994 for the specific purpose of creating quality components designed to support Internet communication development. Dart's development teams carefully design each component for ease-of-use and maximum range of effectiveness for both beginners and advanced developers alike. The results are tools that function in many development environments, such as .NET, Visual Basic, Visual C++, PowerBuilder, ASP, Delphi, C++ Builder and Office. Dart's popular PowerTCP line includes components such as FTP, Mail, Zip Compression, SSL, SNMP, Web, Telnet, and Winsock. These components have enabled the efficient development of applications such as secure electronic trading by a major telecommunications company using an industry specific protocol, the creation of a multilingual bookstore that uses a custom web server without relying on IIS, centralized network management tools for the operation of multinational networks, and an automated database update for outside sales teams on the road. Other applications include adding capabilities to Microsoft Office such as the ability to auto-update an Excel application from an AS/400 server and automating Access to push the latest data to an FTP Server. : These are just a few of the projects the PowerTCP line has helped to create. Companies such as Chase Manhattan Bank, Blue Cross/Blue Shield, America Online, Compaq Computer, American Express, and thousands of consultants and individual project teams rely on Dart's quality code, breadth of capability, and customer service. Designed in object-oriented methods, the tools easily make the change from ActiveX to .NET framework, allowing these users to transition the product as appropriate for their own environments.
