Not sure what the Delphi stuff was on about - not my field. You've
basically got three options for triggering events though:
1. Poll from the client app
2. LISTEN/NOTIFY
3. Some privileged procedural function that writes to a file or sends a
packet etc.
Polling is inefficient, and doesn't sound responsive enough for you.
LISTEN/NOTIFY might be the best bet if your drivers can support it.
