Narrative:

We were swbound on V21; approaching MMM; 12000 ft MSL. Our skywatch system popped a 'traffic' warning; converging aircraft at 200-300 ft below. We pulled up and looked for the traffic; which very soon passed directly under us; at 400 ft or so below. ATC had given us no warning of the traffic at all. We were on an IFR plan.
