Thank you. I have an Input READER_ASCII in use, which need Input::force_update. It reads from a linux pipe. How can we schedule this operation if no network traffic is in the line?

Mit freundlichen Grüßen
Jan Muthreich

One thing to keep in mind for schedule is that it's relative to "network time", i.e., the packet timestamps in the trace. When you say 100s, it's not going to wait for 100s of wall clock time to pass, but will trigger the event once the packet timestmaps have covered 100s.
When working offline from a trace, like in your case, that often feels like "immediately" if the input is short. Could that be it?
