padGetPage
Retrieves the size and resolution of the Transaction Team POS device's touch sensitive surface. This function retrieves the
total number of touch points available on the Transaction Team POS device's touch surface area in the locations pointed to
by Width and Height. It retrieves the dots per inch resolution of the Transaction Team POS device's touch surface area in
the locations pointed to by HorzDPI and VertDPI. NULL pointers may be passed for any parameter to suppress gathering
the associated data. The coordinates retrieved are not display coordinates, they are touch surface coordinates. In general,
touch surface coordinates are much higher in resolution than display coordinates. For example, the Transaction Team 3100
Series' touch surface contains 4096x4096 touch points while the TT3100 Series' display contains only 320x240 pixels, even
though they are about the same size in inches.

is the actual port in use.
