If you do regain any kind of access and don't have a backup, do one as soon as possible as the chances of the system crashing or refusing to boot are greatly increased after such an event so do the backup while you still can (if you still can). But if the system has been going for that long and is still not done, then you can wait a little longer (say another day) just to be absolutely certain or you can bite the bullet, power off the system, and pray it still works or that you can repeat the system repair process. Even if the system boots (and it may not), the chances of trying another repair are greatly diminished.
The problem is that shutting down a system in the middle of a system repair can cause great harm to the operating system to the point that the only option is a clean install (so I hope you backed up you data before you started).
If it's been going on for 12 hours or longer, then it is almost certainly frozen and no longer working. It should only take a couple of hours - with that size disk and depending on how full it is it may take as much as 4 hours or so (perhaps even a little longer).
Read Arduino Card Serial Port Data Using LabVIEW. is a Mac, Linux, Android, iOS, Web Cloud and Windows software publishing website that provides free downloads, daily software updates and sales for trending software with discounts, coupon codes and other promos. The only hardware Set Up required is connecting the serial cable to the serial port on the PC. Those that do not can typically be augmented with a serial interface via PCI slots, USB port adapters, and so on. Most computers include a serial port (typically RS232). 3 Learn LabVIEW 4 Begin Your Application Connecting Instruments via Serial. If it is missing in your VI, then someone must have corrupted the VI and saved it back in the LabVIEW VISA.
The baud rate is connected to the VI connector panel at the 2nd terminal on the upper left. (It is polymorphic with (Instr) and (Serial Instr) versions that are virtually identical. VISA Configure Serial Port is a built-in LabVIEW subVI. Use the pull-down menu to select an instance of this VI. Wire data to the VISA resource name input to determine the polymorphic instance to use or manually select the instance. Owning Palette: Serial VIs and Functions Requires: Base Development System Initializes the serial port specified by VISA resource name to the specified settings.
