Usage Guidelines
If timing-markis configured the TN3270 server will send DO TIMING-MARK as necessary to achieve an end-to-end response protocol. Specifically, DO TIMING-MARK will be sent if any of the following are true:
•The host application has requested a pacing response.
•The host application has requested a Definite Response, and either the client is not using TN3270E, or the request is not Begin Chain.
The use of the timing-markcommand can degrade performance. Some clients do not support timing-markused in this way. Therefore, timing-markshould only be configured where both of the following are true:
All clients support this usage.
The application benefits from end-to-end acknowledgment.
