.Nd bus mouse driver
|
|
.Sh DESCRIPTION
|
|
This is a simple driver for the Logitech and ATI Inport bus mouse interfaces
|
|
designed to be used with the X386 X11R5 X server. The minor device number is
|
|
made up of:
|
|
.Bd -literal -offset indent
|
|
minor = ('unit' << 1) | 'non-blocking'
|
|
.Ed
|
|
.Pp
|
|
where 'unit' is the device number (usually 0) and the 'non-blocking' bit
|
|
is set to indicate "don't block waiting for mouse input, return 0 instead".
|
|
The 'non-blocking' bit should be set for X386, therefore the minor device
|
|
number usually used for X386 is 1.
|
|
.Sh Caveats
|
|
Most bus mice generate N interrupts/second when enabled, whether or not the
|
|
mouse state is changing.
