# NAME

`ms` — Sun workstation mouse driver

# SYNOPSIS

`pseudo-device mouse`

# 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 Xorg(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.
