* 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.
