MS(4)

NAME
ms - Sun workstation mouse driver

SYNOPSIS
ms0 at zstty?

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.

BUGS
ms is hardwired to the built-in zs1 serial port.
