Remarks

The PosKeyboardBase class derives from the PosKeyboardBasic class and contains compete device functionality implemented by POS for .NET for support of keyboard devices. Using PosKeyboardBase, service objects can take advantage of code that implements all of the standard functionality of the device. Service objects that derive from PosKeyboardBase need only provide code for the inherited ClearInputImpl protected method, if necessary, to provide the ability to clear hardware device buffers.
