After adding code that included a VISA wait on event (serial character), my cFP-2220 with LVRT 2012SP1 stopped answering when LabVIEW tries to halt the running code to do a build or deploy...(The code works otherwise works fine).
The code on the controller seems to stop (all activity can be seen halting), but the VISA-part seems to still be hanging, or have crashed the controller (web and ftp interface goes down as well). If I just reduce the given timeout from 100 ms to 50 ms, the problem disappears.
My own interpretation of this is that the rules that is supposed to enable the host PC to halt code on the RT-target is simply not abided by the VISA wait function, and if that function happens to be waiting while the command is issued, and this wait does not happen to time out relatively shortly after the command has arrived, it will cause a crash.
Is this a bug, is there a workaround other than not using events (I changed the code from polling to events to be able to detect 5/10 ms silence time on serial ports without using all processing time on it...), or is it expected and not considered an issue?
