     NAME    [Toc]    [Back]
	  chantab - Channel-to-monitor database


     SYNOPSIS    [Toc]    [Back]
	  /var/X11/Xvc/chantab


     DESCRIPTION    [Toc]    [Back]
	  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.
