### Virtual Keyboard Device Driver

Driver Description:

The Virtual Keyboard Device Driver enables keystrokes to be passed from the keyboard to the DOS session. It also permits text to be pasted from another application into the DOS session as keystrokes. The virtual keyboard device driver permits existing DOS applications that require keyboard access to operate without change.

Compilers/Assemblers Required:

         Microsoft CL386         (supplied with the DDK)

Build Instructions:

1.Set the environment variables so the correct tools are picked up during the build.

    e.g., SET PATH=<drive>:\DDK\TOOLS;%PATH%

Where <drive> represents your DDK installed drive and DDK represents the DDK installed directory. On the CD-ROM, the TOOLS directory path is DDK\ TOOLS.

2.Change the directory to DDK\BASE\SRC\VDEV\VKBD.

3.Invoke NMAKE on the resident makefile.

Files Created By Successful Build:

         Directory:  \DDK\BASE\SRC\VDEV\VKBD

         o  VKBD.SYS
         o  VKBDD.SYS
         o  VKBDSTUB.SYS
