I'm still a diehard, planning to use my Q50s until they die! :) I just haven't seen anything I like better yet....

Anyway, I'm setting up a couple new components. In trying to establish serial control for a Sony TV, I get a constant red from the NC-50 port's indicator light. This occurs on any port I try, and starts immediately when I plug in the cable.

I dug up the old NC-50 documentation, but it has nothing about port indicator light behavior. Does anybody know what the constant red light means? (TV control has not been successful yet, BTW)
