programmatically identifying com ports by their physical port number

[Redstrat]

I have a system with a NI PXI 8420/16 card.  Once in a while a glitch in my PXI system occurs such that my physical RS-232 ports get re-assigned different com port numbers.  Then I have to go into MAX and reassign my aliases to re-align my LabVIEW application with my port hardware.  Is there a way to stop these glitches from happenning?  OR is there a way to programmatically identify a physical port's com number?
