Using the PASSPORT Host Integration Objects for IBM 3270 and 5250 Legacy System Integration

Legacy System Integration with PASSPORT Host Integration Objects - Free Trial Download

PASSPORT Host Integration Objects is a legacy system integration solution that offers a programmatic method of legacy system integration for IBM 3270 and 5250 host applications as a connector to other ActiveX or .NET applications using standard 3270 and 5250 screen information. The non-intrusive solution offers an inexpensive, low risk approach to reusing valuable business processes that have been adapted and perfected over many years. It also replaces the need for terminal emulation.

Running as a background communications module, developers can access the 3270/5250 host application via a well-defined, object-oriented API. You can download PASSPORT Host Integration Objects from this website and review all of the API Documentation and Source Code.

Using PASSPORT Host Integration Objects for Legacy System Integration

PASSPORT Host Integration Objects offers a path to host information at the screen buffer level, allowing you to read and write data to the host presentation space and input fields, open and close sessions, get specific text strings from the screen, create string values, send function keys to the host, switch to other tasks and much more. In doing so, customers can reuse critical legacy applications and proven business logic without making any changes to host code.

PASSPORT Host Integration Objects (HIO) can be used as a programmatic host integration server for legacy system integration, connecting TN3270 and TN5250 host applications with other ActiveX or .NET applications. The Windows 2003 and 2000 Server application includes a TN3270 and TN5250 communications module, an object-oriented API and sample projects and code to use as examples. PASSPORT HIO can be used for server-based integration projects that require a more robust integration tool than what is provided with terminal emulation. Up to 2,000 sessions can be supported on a single Windows server. A terminal emulation control is provided that supports screen display, keyboard, mouse and other functions.

How PASSPORT Host Integration Objects Provides Legacy System Integration

Using Microsoft's Visual Studio (VB, VC++, etc.) or Visual Studio.NET (VB, VC++, C# .NET, ASP .NET, etc.), you can create composite enterprise integration applications that require fast, reliable access to existing IBM 3270 or 5250 applications.

PASSPORT Host Integration Objects, based on the IETF OHIO (Open Host Interface Objects) draft, includes direct TN3270 and TN5250 connectivity to critical legacy applications using IP. Separate terminal emulation is not required for host access. Sample programs, documentation and a test program that demonstrates the use of each object Method, Property and Event are included in the Zephyr development solution.

How PASSPORT Host Integration Objects is Licensed

Available via an annual subscription-based license that includes the cost of the software, access to technical support and all product upgrades, PASSPORT Host Integration Objects offers one of the most inexpensive approaches to enterprise legacy integration.
