2000/1012		* 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.
2001/0404		* * 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.
