The combination of Tell About Delay set to N and Wait Across Delay set to N is not allowed.
If Tell About Delay and Wait Across Delay are both set to Y, an intermediate return code of 220 is returned when communication is lost with the database. If the request is still pending, the response’s final status will be returned after communication is restored. That is, if Wait Across Delay is set to Y, the notification it supplies is the one at the end of the waiting period, and the notification that Tell About Delay does, or does not, supply is an additional one during the waiting period.
The Fetch, Rewind, End Request, and Abort functions read and use the value of Tell About DelayCrash, but do not store it.
