The pen user interface (PENUI.DLL) library contains the user-interface functions of the pen Unidriver. These functions provide a simple configuration dialog box that queries for the pen device model, the COM port, and whether to provide OEM-specific data (if the tablet supports it).
If desired, an OEM developer can replace or enhance the user interface, by providing a property sheet for Windows 95, thus gaining additional marketability and user recognition. The pen Unidriver maintains its interface code as a separate library to facilitate such enhancements or a complete replacement of the library by the OEM.
The sample pen user interface source code is in the directory \PEN\SAMPLES\PENUI of the installed Windows 95 DDK. This sample can be enhanced or used as a model for the source code of a DLL that completely replaces the pen user interface library.
