I have DSL and a 10-base-T home network (five computers) at home. I don't
interfere with them, and they don't interfere with me at all.
I may be just lucky on these computer issues. I make up for it in another
area though -- I monitor this reflector because of my severe and
continuing-for-years line noise problems.
