LabVIEW
Resetting Vi
Solved!
I see other threads that deal with resetting VI problems but none that appear to have the answer that sorts my specific problem.
I have a program that started with the read/write basic serial example. I then modified the example to only a read function, as the serial device connected uses asynchronous string, instead of ask and get commands. Then program sorts and matches string components to display the data appropriately to the user. This program is simple and works well on one of my staff's computer using Window 7 Enterprise (dell latitude) but the same program run on the second staffs PC (Lenova ThinkPad) with window 7 enterprise seems to either crash or lock up. The same program on each but the Thinkpad always locks up showing a resetting vi box, and is causing the PC to lock up and they need to use task manager to force it closed. The only difference I can see is the serial port converter (pig tail). One PC uses one type the other a second type.
conversely, I removed the stop (abort) function on the application and programmed the Vi to finish a cycle before closing the program, but even that did not fix the problem. Any suggestions or advice would be appreciated.
Did you try switching the USB to Serial adapters? I have had HORRIBLE luck with USB to RS-232 adapters. I don't trust them as far as I can throw them. But if you find a set that works consistantly, stick with those.
The other possibility related to the USB would be the "power saving feature" that Window 7 has where it will turn off a USB hub's power. You can disable that through the device manager.

USB-serial converter cables use different chipsets.
I ran into this issue this week. One cable seemed to work when using TeraTerm but would fail when LabVIEW was being used.
