If I have the API for my PTZ camera, is there anyway to have the PTZ commands forced through the generic driver I am using now?

Here are some API example commands:

This is for a Visualint camera

Perhaps DriverCommand will fit..

We have no samples using this, hopefully you can use the information from the documentation link.
