If a TCP listener is configured to not accept an ASCII payload, then any outbound reply message that is sent by the listener will not contain a termination character sequence. In this situation, the </ListenerRequest> XML tag acts as the termination sequence to delineate a complete request on the inbound side and the </ListenerResponse> XML tag acts as the termination sequence on the outbound side.
If a listener map using this listener is configured to send an ASCII reply, the payload that is delivered to the TCP application will not contain a termination sequence. If you want to use an ASCII outbound payload, you must append a character termination sequence to the ASCII payload definition in the listener map. For more information, see Listener maps.
