Easily add Telnet and remote access communications capabilities to any .NET application

Overview

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.

If you are looking for a VT52, VT100, VT220 or VT320 emulation control, please view the PowerTCP Emulation Tool.

• 100% managed code!
• Common Telnet options are set using collections of options, and are automatically negotiated when the session is established.
• Telnet, rlogin, rsh, and rexec components can be used to access a real-time UNIX data source.
• Design-time visual interface supports interactive editing of client and server options.
• Execute allows Rsh and Rexec components to send commands and capture responses in one line of code.
• Scripting made easy with Login and WaitFor method.
• AutoReceive technology reduces code by managing all incoming data.
• More advanced options for Telnet can be easily programmed (samples are provided).
• Supports SOCKS4 and SOCKS5 proxies.
• Comprehensive Stream-based design provides flexibility.
• Supports International character sets.
• Fully supports in both event driven (asynchronous) and blocking (synchronous) application designs.
• All components provide multi-threaded asynchronous functionality.
• All components allow user-interface events to process during synchronous use.
• All components are thread-safe on critical members.
• Debugging has been extended beyond run-time testing to a design-time Editor in every component that tests server operation without compiling. A real-time visual interface provides unprecedented debugging capability.
• Compliant with RFC 854
• Includes a royalty-free license.
• Integrated Help 2.0 documentation includes over a dozen tutorials and a comprehensive reference guide with full support for dynamic help.

Uses/Applications

Some uses of PowerTCP Telnet for .NET include:

• An automated Windows Service that executes Telnet commands.
• Custom Windows .NET front-end applications for Telnet sessions. Your users will never have to learn UNIX shell commands.
• Using the Rexec or Rsh components, run any UNIX command or script and display the result in any format.
• From an ASP.NET back end or a Web Service, run SQL commands on a UNIX server, and display the results within the browser.
• Control or query network devices such as switches, routers, terminal servers, hosts.
• With only a few lines of code you can upload data to a UNIX host, process it, and bring back the results.
• Create a proxy by redirecting Telnet or rlogin communications between the network and any local device (COM port, etc).
