Sadly the situation is quitly political more then tecnical. You know how sometimes logic goes lost in political decicions. I am sadly not able to change external.sh nor ask for an update. I hoped actually to solve that in my PERL-Program. Like greping the child-process and send STDIN there or something like that. And "Somebody" left the company and (lucky guy) went to Australia 2 years ago. He was a nice guy who would have bypassed the political decicion in order to get things done.
