.Sh SYNOPSIS
.\" XXX this is awful hackery to get it to work right... -- cgd
.Cd "pms0 at isa? port" \&"IO_KBD\&" irq 12
.Cd "pms0 at pckbd? irq 12
.Sh DESCRIPTION
This driver provides an interface to a PS/2 auxiliary port mice.
This driver provides an interface to a PS/2 auxiliary port mice. The driver
internally converts the PS/2 mouse output into the busmouse protocol.
.Pp
Information can be retrieved from the driver using an ioctl() call or
by reading the device directly using read().
.Pp
The MOUSEIOCREAD ioctl, found in machine/mouse.h, returns a struct mouseinfo.
.Pp
When reading the mouse device directly, each change of button state or
mouse movement generates a five byte event.
The bytes contain:
.Bl -tag -width -offset indent -compact
.It 1
Button status. (u_char)
.It 2
Right/left movement. Positive values indicate right, negative
left. (char)
.It 3
Up/down movement. Positive values indicate up, negative down. (char)
.It 4
Reserved. Should be zero.
.It 5
Reserved. Should be zero.
.El
.Pp
The direction bytes are signed characters, giving a range of +127 to -127.
A positive value indicates movement to the right or up, and negative left
or down.
