DESCRIPTION
The
ms driver provides an interface to the workstation console mouse. This Mouse Systems three-button device produces five-byte blobs of the form:
b dx dy dx dy
where “b” is the button state, encoded as 0x80|(~buttons) -- there are three buttons (4=left, 2=middle, 1=right) -- and “dx” and “dy” are X and Y delta values, none of which are in the range [0x80..0x87].
The device special file /dev/mouse is used to get direct access to the mouse input stream. The following ioctl's are supported (mostly just enough to keep the X(1) server going):
-
VUIDSFORMAT
-
Set translation mode. The argument is of type int *, the only value supported is VUID_FIRM_EVENT.
-
VUIDGFORMAT
-
Get translation mode. The argument is of type int *. VUID_FIRM_EVENT is always returned.
OPTIONS
The mouse driver can be configured using the following kernel configuration file options.
-
options SUN_MS_BPS=integer
-
This option causes the kernel to communicate with the mouse using the serial baud rate integer. It is useful for mice which do not communicate at 1200 baud.
