Operating commands are skipped instead of being executed. The following default information is set as the command execution result (return information of the dc_adm_call_command function):

• Shell termination code: 0
• Data output to standard output or standard error output: Null character
• Output data length (standard output or standard error output): 0

Instead of the operating command being executed, the data in the operating command result data file is set as the command execution result. When the UAP issues a dc_adm_call_command function, the online tester reads the execution result data from the file and returns the data to the UAP.

An operating command result data file must be created for each service. Set the execution result data in this file before running a test.

If the dc_adm_call_command function is issued more than once in a service, the user must create the data to be returned at each function call. This also applies to the main function in the SPP and to functions issued from an SUP.

Figure 2-10 shows how the data in the operating command result data file is used to replace the actual execution result.
