[HELP] how to trigger a callback from an external...

Andre-

I believe you're gonna be stuck with SendCardMessage. I've had an
enhancement request sitting in Bugzilla for a while (as of next week
it'll be five years) to modify the scope of SendCardMessage, but I
wouldn't wait around for it. You can always send a uniquely
identifiable message such as "soapdog_Incoming" and catch it in the
stack script.
