Then I saw the light. About a year back, when I upgraded my motherboard, I
held on to the "old" serial cable/connector. That's a no-no. Apparently,
each serial connector is (potentially) customized for the MB despite the
same plugs at both ends. That seems kind of obvious now but I didn't pay
that much attention. Once I fixed that, LIRC worked like a charm.
