This processing causes a CLEARtextRESUMED notification to be given to the telnet server and results in the assertions because the telnet server does not handle the CLEARtextRESUMED notification. SOLUTION: The Telnet server is modified to handle the CLEARtextRESUMED notification. The parts changed are: TNSTMAS PASCAL, MSTCP MSGS, TCPRINT PASCAL and TCNOTIF PASCAL.
