I recently upgraded my LV from 5.1 to 7.1, simultaneously went from Solaris 5.5 to 5.8. The old code doesn't seem to work anymore. Specifically, the VI hangs up forever on FindDevLA.vi. I think this function may be obsoleted: it still appears on the Instrument I/O function palette but there's nothing about it in the function reference help. Tried it on another Solaris 5.8/LV7.1 machine with same result. So, does anybody know if this function works in this environment, and if not, any comments on the most efficient way to bring it up to snuff? Kevin Redmond (redfoot)
