VISA drivers are also a total nightmare, with one vendors code, not
working well (if at all) with another vendors "VISA" subsystem.
Also, often when you install another VISA libraray to support some
instrument or application, it fouls up other existing drivers and app's.
Plus, as already been mentioned, it's all "Windows only" anyway.
Avoid VISA for Ham stuff at all costs!
