I downloaded the user manual from Asus for the production and it appears that there is no pclink software for this product. I am guessing that PCLink is only for the Zenfones.
Unfortunately, this disqualifies the product for my purpose. I originally considered this for my mom for use to replace her Nexus 7. However, I need to be able to remote access her tablet to fix stuff for her, otherwise a simple fix would take an hour to walk her through. Lately I have been using teamviewer.
In the past, I had use VNC,but it appears that the rootless version of vnc vmlist may not be usable on Marshmallow or later. There is currently no way to root Asus Zenpad 3s 10 at the moment, so regular vnc servers are out.
