Check for loaded driver

Hi.

Does anyone know of a method to determine if a particular driver name is loaded within a running application?
I haven't found anything within the Indusoft Technical Reference.
I have applications which interface with a range of different devices in varying configurations.
It would be really handy to have a function something like:

IsDriverLoaded("ABTCP")

which would return TRUE/FALSE depending on whether the named driver is loaded within the running application.

My applications environment is Indusoft v7.0.
