CKS

Place the CKS command in a test script to verify the Checksum value generated for the test. This is a means of providing an additional layer of security to the test script. Adding the CKS command to a test script does not cause NETS to verify the CKS value assigned for the test script. Additional information is required to verify the checksum value of a test. For more information on CKS, refer to Appendix G of the NETS Programming Manual 132-06047-0006
