Introduction to PowerTerm WebConnect OCX Control

PowerTerm WebConnect OCX Control with Open API is Ericom Software's browser-based, Web-to-host connectivity solution, which can be deployed immediately and can also be customized. The output sent to a client's device is an OCX Control, which is embedded into the HTML Page or a Visual Basic application and programmable on the client side (using JavaScript or VBScript). PowerTerm WebConnect OCX Control features single point (zero client) installation and centralized management, which gives the administrator a high level of control.

A key advantage that PowerTerm WebConnect OCX Control has is that this advance product uses nothing more than the robust and powerful, well-known and carefully debugged PowerTerm emulation engine, which is embedded in the HTML page or a Visual Basic application and exposes methods, events and properties to the client-side scripts. This allows any alterations and adjustments made to the original AS/400 or VT application to be reflected in the resulting web application totally "on-the-fly".

PowerTerm WebConnect OCX Control can be used in any Web scenario or a Visual Basic application where interaction with legacy systems is required and where cost effectiveness, time to market and non-intrusiveness are important.
