Logic aside, I have watched it carefully while I was working there this morning, and it blinked occasionally when I was not touching either keyboard or mouse. OTOH, it could be a sort of ping to the transmitter, I suppose, but if it were that I'd expect a regular pattern. I'll try the old PS/2 keyboard and mouse next time I have a longish session with the server. If I get any likely answers I'll let you know. Thanks for the help.
