If your driver has a varian::report method like other drivers then you can do

asynReport 10 portName

where portName is the asyn port name of your driver.

That will dump the entire parameter library with index numbers, drvInfo strings and parameter values.

You should see the parameters from asynNDArrayDriver first, then the ones from ADDriver, and finally the ones from your Varian driver.
