Screen-settling procedure

ZIETrans performs screen-settling in two distinct operations
  • Analyzing outbound data
  • Waiting for operator information area (OIA) flags
When analyzing outbound data, ZIETrans performs one of several strategies that analyze the outbound data, trying to determine when the host application has finished sending data. Each of these strategies is used in different cases and each has settings that customize its behavior.

When waiting for OIA flags, which is independent of the strategy used in analyzing outbound data, the session's OIA flags are examined to ensure that the host is ready for the user to send more inbound data. There are also settings that customize this behavior.
