.Dd February 17, 2017 .Dt MS 4 sun3 .Os .Sh NAME .Nm ms .Nd Sun workstation mouse driver .Sh SYNOPSIS .Cd "pseudo-device mouse" .Sh DESCRIPTION The .Nm driver provides an interface to the workstation console mouse. This .Tn Mouse Systems three-button device produces five-byte blobs of the form: d -literal -offset indent b dx dy dx dy .Ed
p where .Dq b is the button state, encoded as .Li 0x80|(~buttons) -- there are three buttons (4=left, 2=middle, 1=right) -- and .Dq dx and .Dq dy are X and Y delta values, none of which are in the range q Li 0x80..0x87 .
p The device special file
a /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 c X server going): l -tag -width VUIDSFORMAT t Dv VUIDSFORMAT Set translation mode. The argument is of type .Fa "int *" , the only value supported is .Dv VUID_FIRM_EVENT . t Dv VUIDGFORMAT Get translation mode. The argument is of type .Fa "int *" . .Dv VUID_FIRM_EVENT is always returned. .El .Ss OPTIONS The mouse driver can be configured using the following kernel configuration file options. l -tag -width VUIDSFORMAT t Cd options SUN_MS_BPS=integer This option causes the kernel to communicate with the mouse using the serial baud rate .Va integer . It is useful for mice which do not communicate at 1200 baud. .El .Sh SEE ALSO .Xr sun3/kbd 4 .Sh BUGS .Nm is hardwired to the built-in .Em zs1 serial port.
