Pascal,
great! I first wanted to confirm that I am on the right path because I
actually never looked at the code before today. Yes, I am willing to
continue and submit a pull-reqeust in Gerrit. If possible, I'd add
support for it step-by-step. For now I can only confirm that it works
for those two channels present in the patch.
Thanks
