Enterprise Server CICS terminal control is configured to discard all unsolicited TN3270 messages, i.e. it will discard TN3270
                  messages that arrive while a transaction is active for the target terminal unless the transaction has issued an explicit CICS
                  RECEIVE after the first CICS terminal control command. For messages that arrive while the terminal is idle, ES will attempt
                  to start a transaction for the message.
