DDS manual says:
" On a read operation from invited devices operation to a display file, only data from devices with an
outstanding invite operation are considered. The input operation waits for data from any of the invited
devices. (See the WAITRCD parameter on the Create Display File (CRTDSPF) and Change Display File
(CHGDSPF) commands.) If none of the invited devices responds before the wait time ends, a notify
message is sent and no data is returned."
So, no data is returned when the notify message (Status=1331) is sent

Subject: Using a timeout with display files
Caution: This email originates from outside of Fresche | Attention: Ce message provient de l'extérieur de Fresche
Dear friends:
A few weeks ago, I inquired about something related with the subject, to which I could achieve what I was looking for.
The goal was to allow the user to type in data on a few display fields within a given period of time (say 30 seconds). If that period of time went off, then control is given back to the program and take some actions.
Of course, we're talking about an RPG program here.
Now, since there is no key pressing in this scenario, the input buffer is then NOT updated, so whatever the user could have typed in, none of that can be retrieved.
I've been asked to find out a way to keep that typed in data and have it back to the program as though the user pressed either Enter or another function key. Much the same as the attention keys, I know no input buffer is updated when giving control back to the program. That is what the user does NOT want.
So, is there any way to force the system like "hey, after 30 seconds, could you please pretend the Enter key or (say) F6 key was pressed, so as to have any typed in data available to the program?"
Is that possible? If not, any ideas on how to get that approach?
Thanks in advance.
