### Device Driver Test Tool and Suites: Parallel Port

Tool Description:

The Functional Verification Tests (FVTs) for parallel ports exercise the Application Programming Interfaces (APIs) defined for the DosDevIOCtl interface of parallel port device drivers. The tests are implemented with the Device Driver Test Tool (DDTT). Each test is defined in a script file that can be modified using a text editor to create additional, specialized test cases. The test scripts give the user a repeatable set of tests that demonstrate parallel port function and performance. Errors are reported and isolated to a specific test sequence and API.

User input and output from each thread of the parallel port tests is performed by way of a separate Presentation Manager window. Test cases log all information to log files that clearly indicate the actual execution sequence for error-tracking purposes.
