| 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. |
