KH>> Well, Jean, I tried this (approx. 20 foot) cable...

 AB> 6m is probably a bit long for a parallel cable.

i've installed quite a bit longer in extreme cases... yes, parallel... i
believe the longest was 50 feet... in an office, up over the ceiling tiles
and down to the laser printer...

granted, it was "special" cable... "special" in that it
was of very high grade, extremely well shielded, and very heavy...
