     NAME
          chantab - Channel-to-monitor database


     SYNOPSIS
          /var/X11/Xvc/chantab


     DESCRIPTION
          chantab describes the monitor type that is connected to a
          server's video channel.  The server uses this information
          with a description of the monitor in the moninfo database to
          determine whether the connected monitor has the capability
          to run given video formats.

          The format of each entry in the chantab file consists of the
          channel number and monitor type name separated by a space.


        Channel Designator
          The channel designator must be the first item on a line and
          is composed of three pieces:

                    server.screen.channel

          The server and screen numbers take their normal values as
          referred to by X.  The channel number is as treated by
          XSGIvc and labeled on hardware.  The three values are
          separated by a period (.)  character.


        Monitor Type Name
          The name you specify as the monitor must be a monitor type
          name given in the moninfo database.  If you supply a name
          that is not known, the server uses the type "default".

          The monitor type "default" is reserved and is not a genuine
          monitor type name.  If you use default as the monitor type
          name, the server uses the default values provided in the
          moninfo database in responses to users.  It is likely this
          information will not be correct, thus it is recommended you
          supply the correct monitor type name.

          Some servers have the capability to query the monitor type
          from the monitor itself.  If the monitor type name you
          supply is preceded by a question mark (?), the server will
          query the monitor type from the monitor.  If the query is
          successful, the server will use the monitor type reported by
          the monitor instead of the monitor type you supply.  If the
          query fails, the server uses the monitor type you supply.
          Queries are performed only during server initialization.
          Some monitors can report unique serial numbers that will aid
          in identification and correlation to a specific channel. You
          specify the serial number as a string enclosed in
          parentheses on the same line as the monitor type.


        Comments
          Any line whose first character is the pound sign (#) will be
          treated as a comment.
