Gene, The rewiring is indeed something of the past. I did just the same, had a very simple breakout with rc filtering and switching the pins to comply with the xylotex. But since the changed hal, there is no need anymore.
Ha. Hope the guy measured before using this cable! I'm assuming there won't be a cable fault as it is still the same. Also I'm measuring with the scope at the output to the xylotex, so should be ok. Just made a small pulse generator. Will make a DB25 to attach it directly to the xylotex to test. I'm getting more and more convinced that it will be something small and related to the output of the pc. Ran fine before. Only: unused for 2 months and ubuntu upgrade.
