BS2+Seetron''s G12032 graphical LCD+Pak6 + mouse to capture mouse move

What I would suggest is to put the mouse in remote mode. Then the mouse
remembers a cumulative reading until you ask for it.
Keep in mind the mouse has a sampling rate and it is possible to overrun
that rate even on a PC. Try writing a DOS or Windows program that plots
each point you get from the mouse and then move the mouse rapidly across
the screen. You won't get every point. So if you are moving in the X
axis you might get: (100,50) (110,50) (130,50). The slower you move the
mouse the more points you get.
In remote mode, the movement is relative. So when you ask for a report,
the result is (0,0) if the mouse hasn't moved sine last time you asked.
This is the method used in this program:
