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