- * byte 1 - DX
- * byte 2 - DY
- *
- * shift & right button is the same as middle button
- *
- * Intellimouse and AccuPoint with extra buttons deliver
- * byte 3 - 00 or 01 or FF according to extra button state.
- * extra buttons are mapped in this code to buttons 4 and 5.
- * AccuPoint generates repeated events for these buttons;
-* it and Intellimouse generate 'down' events only, so
- * user-level code is required to generate button 'up' events
- * if they are needed by the application.
- * Also on laptops with AccuPoint AND external mouse, the
- * controller may deliver 3 or 4 bytes according to the type
- * of the external mouse; code must adapt.
- *
- * On the NEC Versa series (and perhaps others?) we seem to
- * lose a byte from the packet every once in a while, which
- * means we lose where we are in the instruction stream.
- * To resynchronize, if we get a byte more than two seconds
- * after the previous byte, we assume it's the first in a packet.
