If the TPF system is waiting for a response to a command and no response is received before the SSCP time-out interval expires, a pseudo negative response is created and passed to the command router. The command router passes the response to the appropriate response handler for action. The action taken by the response handler for timeout processing is CLNUP. See Appendix I, TPF Sense Code Processing for information on negative response processing and the CLNUP action.
