32 .Nd PS/2 mouse style pointing device driver
47 driver provides support for the PS/2 mouse style pointing device.
51 As the PS/2 mouse port is located
60 Basic PS/2 style pointing device has two or three buttons.
63 The PS/2 style pointing device usually has several grades of resolution,

84 The PS/2 style pointing device typically supports 10, 20, 40, 60, 80, 100
94 The current operation level can be set via an ioctl call.
96 At the level zero the basic support is provided; the device driver will report
99 The movement and status are encoded in a series of fixed-length data packets
102 This is the default level of operation and the driver is initially
103 at this level when opened by the user program.
105 The operation level one, the `extended' level, supports a roller (or wheel),
108 8 byte data packets are sent to the user program at this level.
110 At the operation level two, data from the pointing device is passed to the
