For example, my application needs to get the tablet's model from the driver. But the driver only knows the model after it communicates with the tablet. So, the model can not be assigned into an option in the config file. Basically, I don't have problem to sent data to the driver from client. I use xfWcmDevChangeControl(), which is assigned as local's control_proc to send data to the driver. I have problem to pass data from driver back to the app. That's why I let driver write to a file so the app can read from there. >There are definitely sufficient option handling interfaces available to drivers so that you don't >need to go digging into the OptionRec.

In addition to the use and testing from individual users, it is also tested by many corporation users. We support all the tablets that Wacom has released so far. In fact, we had made some more changes since I submitted my last patch (Oct. 10, 2003). But, we'll wait a bit to see more testing results before making a new patch.
