NAME

Xcvc − Cornerstone Smart Board Interface server for X11

SYNOPSIS

Xcvc [ option ] ...

DESCRIPTION

Xcvc is the server for INTERACTIVE X11 running on an INTER­ACTIVE UNIX Operating System Version 2.2 or later, using any display adapter based on the Cornerstone Technology CVC 1 or CVC 2 display controllers. 

Xcvc operates on a 386- or 486-based ISA or EISA computer.  It is normally invoked by a program such as xinit(1) or by the INTER­ACTIVE Easy Windows Environment. 

OPTIONS

Options are described under Xserver(1).

CONFIGURATION

Xcvc requires the Type field in the configuration file (see Xconfig(5)) to be CVC. 

The Info field must contain at least the screen dimensions.  It can also contain the number of colors (gray levels), the screen resolution, and the starting physical address for video memory, although Xcvc has reasonable defaults for each of these.  Entries in the Info field are blank-space separated and can appear in any order.  The entire field must be enclosed in double quotes unless there is only one entry in the field.  Possible entries are as follows:

Screen size in inches in the format xinchesxyinches. 

Number of “colors” (gray levels).  The default is 2 (monochrome), which is all the current version of the server ­supports. 

Video memory physical location in the format locm where loc is an even number between 2 and 14.  This is the starting address in physical memory to which the video memory’s 2-MB area is mapped.  The default is 12m, meaning a start address of 12 megabytes.  This should not be changed unless the location interferes with other hardware in the machine.  Check carefully before using an address of 14m because some machines may have other uses for the extreme high end of the 16 MB memory space.  (The CVC boards decode an entire 2 MB of address space.) 

Screen resolution in the format xpixelsxypixels.  This should only be specified for “new” boards.  Normally, the server determines the resolution from the identification returned by the board itself; an explicit resolution value is required only for a board type unknown to the server.  If the board type is known to the server and the resolution is specified in the Info field, the specified resolution must match what the server expects; no override is possible. 

Xcvc supports a variety of display systems based on the Cornerstone video controller hardware.  Supported display systems include at least the following:

Cornerstone DualPage, SinglePage XL
ADI AD-1700, AD-1901
Compugraphic Dawn WS
CPT Full-Page WS
DesignView 19/E
Hyundai HGC-1280
Panasonic M19/15 AT
Princeton IMAGER
Samsung OnePage
SYSDYNE! PC 19PW
Tatung GC-1580
Taxan Crystal View

For Version 2.0.1 or later, Xcvc supports the Cornerstone Video Controller PC202A-19 using a DualPage D20A/0191 monitor. 

The following configuration file entry fully specifies display 0 to be a standard Cornerstone DualPage display running on a screen 14.5 inches wide and 11 inches high:
