If you open a Telnet session through a terminal server to a console input, then there will be no prompt. While testing manually, you submit a carriage return (CR) by entering an empty command after the session is opened. During execution, Spirent iTest uses a prompt to know when to submit the next command, but if there is no prompt at the start of the session, then the CR step will timeout. Follow this procedure to avoid the problem: 1. In the Test Case editor, select the open step for the Telnet session. 2. In the Step Properties section, click Telnet Step Defaults > Completion. 3. Set Completion Criteria to Idle. This forces the step to end if there is too much time without activity and then starts the next step starts immediately (to send out the CR).
