Hi there! This is a somewhat special question which has not so much to do with linux-audio stuff - but as there are quite a few people here dealing with electrics / electronics and some of them even earn their money as event technicians you might get in touch with special measurement equipment like a VDE 0701/0702-tester. As you might know, most manufacturers of those devices offer software to ease the administration of your testing pool, but most of them still life in the 90s and make them windows only. So here I am, asking you if you are using or knowing a VDE 0701/0702 -testing device manufacturer that is modern enough to master the (not so secret) secrets of cross-platform software engineering or opened their devices and protocols in that way, that I can easily access them with linux / open source tools. Greets! Mitsch
