I'm of the opinion that one should never underestimate the ability of people to attempt to shoot themselves in the foot. However this is only a debugging interface so you do make a good point. I guess I'm worried that some idiot is going to set it to 2 baud or 2 billion baud for some dumb reason then come complaining to us when their wireless card crashes or locks up or something. Maybe we can just sweep this all under the carpet by putting all the debug uart stuff behind some nice #ifdef. > That's my perspective on the issue, but I recognize other opinions may > differ.
