PLUG: Plug and Play Diagnostic Tools THIS TOOL IS NOT SUPPORTED BY MICROSOFT CORPORATION. IT IS PROVIDED 'AS IS' BECAUSE WE BELIEVE IT MAY BE USEFUL TO YOU. WE REGRET THAT MICROSOFT IS UNABLE TO SUPPORT OR ASSIST YOU SHOULD YOU HAVE PROBLEMS USING THIS TOOL. DTPL.EXE is a tool designed for interpreting the tuples on a PC card and is intended to help you design or verify card information structure (CIS) for use with Microsoft's future implementations of Personal Computer Memory Card International Association (PCMCIA) support in Microsoft(R) Windows(R). For more information on these implementations, refer to the appropriate developer's kit and documentation, which can be obtained from Microsoft's Hardware Vendor Relations Group, ihv@microsoft.com. DTPL.EXE displays information derived from the tuples on the PC card, including the Plug and Play (PnP) device ID, the PnP logical configurations, and a display of each tuple on the card. To allow tuples to be interpreted without the need for a real-mode card services driver and to be tested before they are placed on a PC card, the tuple input can also be taken from a file. The tuples in this file must be defined in an ASCII HEX format, and each hexadecimal value must have two digits. DTPL.EXE runs in real-mode on MS-DOS(R), using real-mode card services and socket services implementations. It is intended to be run on PC cards that have not been configured by a card services client or enabler. For this reason, card services clients and PC card enablers should not be loaded or active when using this tool. ISOLATE is a program for use in either a Windows or MS-DOS environment. It has not been run under Windows NT(TM), and will likely cause some form of protection violation because of how input/output (I/O) is performed directly to the ports. ISOLATE will isolate each Plug and Play card and assigned it a card select number (CSN). The cards are then queried for their configuration information which is parsed and displayed to the user in a useful format. This provides a way to check the expected programming of the card with what is already present. DTPL.EXE, ISOLATE, and PNPBIOS are all intended to be diagnostic tools for Plug and Play devices.
