### Evaluation of Test Case Results

Unless otherwise stated in the test-case descriptions, all test cases are expected to succeed. If a test case fails in a mode detectable by DDTT, then the token "ERROR" will be written to the corresponding log file.

The script files test all of the different parallel port functions. After each script file has finished executing, it will log all of the test information out to a log file. When all of the script files have finished executing, the command file will search all of the log files for any errors that have occurred. The results from this search are stored in the RESULTS .TXT file.

When the command file has completed searching the log files, it also displays the results on the screen. The command file is searching only for the word "ERROR".
