Yes, seems also a bit risky to me. I used identical wire for the signal lines, as short as possible. I think, they should have the same imperdance (taken from the same cable).
I think, I will stick to the port savers and do what these ladies at the telephony compaines did some decades ago: Plug in, Plug out. Maybe, once I find an electronic switch at a nice price, I will try it again. -Peter :) ---------- >Von: <[EMAIL PROTECTED]> (Quadlist) >An: <[EMAIL PROTECTED]> (Quadlist) >Betreff: Quadlist Digest #1194 >Datum: Mon, 10.
