ABSTRACT:
A method of operating a computer which has a CPU, an input/output coprocessor, and an attached pointing device, the input/output coprocessor receiving data in packets from the attached pointing device. When the coprocessor receives data from the pointing device, if the pointing device produced the data in response to a command from the CPU, the coprocessor passes the data unmodified to the CPU. When the coprocessor receives data from the pointing device, if the pointing device did not produce the data in response to a command from the CPU, the coprocessor requires the remainder of the data packet to appear within one second before passing the packet of data to the CPU.
