Usage Guidelines
If timing-mark is 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-mark command can degrade performance. Some clients do not support
timing-mark used in this way. Therefore, timing-mark should only be configured where both of
the following are true:
• All clients support this usage.
• The application benefits from end-to-end acknowledgment.
Example
The following command enables TIMING-MARK transmission:
timing-mark
