Description

IBM® Rational® Test Virtualization Server software facilitates timely and regular testing throughout the development process. By virtualizing portions or the entirety of an application or database, it eliminates dependencies, allowing software testing teams to initiate their work without waiting for those resources to become available. This approach helps decrease the expenses associated with setting up and managing complex application environments. Furthermore, it promotes agility and predictability through continuous integration testing implemented earlier in the development cycle. Seamless integration with IBM Collaborative Lifecycle Management enhances collaborative testing efforts. The virtualization features include data-driven and correlated response sequences, as well as comprehensive stateful database emulation. A centralized repository for virtualized environments allows for the reuse, deployment, and alteration of configurations to explore various testing scenarios. In addition, IBM Rational Test Virtualization Server encompasses all functionalities found in IBM Rational Performance Test Server, supporting the validation of application performance effectively. With these capabilities, organizations can ensure that their applications are rigorously tested and optimized before deployment.

Description

The Virtual Serial Port Driver, developed by Electronic Team, is a utility that simulates a serial port and pairs it with another virtual serial port through a virtual null modem cable. The software is capable of fully replicating the settings of real serial ports, including support for HandFlow control and signal lines, ensuring that the virtual ports are recognized by the operating system as if they were standard hardware serial ports. Data transmitted to one virtual COM port is instantly mirrored in the other, creating a seamless communication link. Once a pair of virtual serial ports is established, they can be located in the Device Manager and are ready for use right from system startup, even prior to user login. For developers looking to incorporate this functionality into their applications, the Virtual Serial Port Driver can be integrated using a DLL, ActiveX, or through core level usage, allowing for the direct creation and management of virtual COM ports within their software environment. This integration capability provides flexibility and enhances the functionality of applications that require serial communication.
