the states of the 4 quadrature signasl and the <n> buttons are all
available simultaneously on the interfce connector. Yes, you have to
look for changes in signals to see if/how the mouse is moving, but I
don;t think that makes it serial.
Perhaps, but when was the last time that you saw a new quadrature
mouse being offered for sale? Mice today universally communicate
using a single serial bit stream.
