US 5,691,926 A · Integrated test tools for portable computer

Abstract

A system for providing test tools at a remote location with a portable computer is disclosed. The system includes a peripheral interface coupled to the computer for communicating data between the computer and a unit under test. The test tool is implemented on a printed circuit card that, preferably, conforms to the dimensions and specifications of the card categories for the Personal Computer Memory Card Interface Association (PCMCIA) standard. The test tool receives and transmits signals to and from the unit under test so that an application program executing within said computer may display, analyze, or otherwise use the data received from the test tool which is controlled by the program. The test tool includes a tuple to identify the functionality of the tool. A card service interpreter within the computer communicates with the tool in accordance with the tuple information identifying the test tool.
