	default 24 if !NX_DISABLE_24BPP
	default 32 if !NX_DISABLE_32BPP
	---help---
		Currently, NxConsole supports only a single pixel depth. This
		configuration setting must be provided to support that single pixel depth.
		Default: The smallest enabled pixel depth. (see NX_DISABLE_*BPP)

config NXCONSOLE_CURSORCHAR
	int "Character code to use as the cursor"
	default 137
	---help---
		The bitmap code to use as the cursor.  Default '_' (137)

config NXCONSOLE_MXCHARS
	int "Max Characters on Display"
	default 128
	---help---
		NxConsole needs to remember every character written to the console so
		that it can redraw the window. This setting determines the size of some
		internal memory allocations used to hold the character data. Default: 128.

config NXCONSOLE_CACHESIZE
	int "Font Cache Size"
	default 16
	---help---
		NxConsole supports caching of rendered fonts. This font caching is required
		for two reasons: (1) First, it improves text performance, but more
		importantly (2) it preserves the font memory. Since the NX server runs on
		a separate server thread, it requires that the rendered font memory persist
		until the server has a chance to render the font. Unfortunately, the font
		cache would be quite large if all fonts were saved. The NXCONSOLE_CACHESIZE
		setting will control the size of the font cache (in number of glyphs). Only that
		number of the most recently used glyphs will be retained. Default: 16.
		NOTE: There can still be a race condition between the NxConsole driver and the
		NX task.  If you every see character corruption (especially when printing
		a lot of data or scrolling), then increasing the value of NXCONSOLE_CACHESIZE
		is something that you should try.  Alternatively, you can reduce the size of
		MQ_MAXMSGSIZE which will force NxConsole task to pace the server task.
		NXCONSOLE_CACHESIZE should be larger than MQ_MAXMSGSIZE in any event.

config NXCONSOLE_LINESEPARATION
	int "Line Separation
	default 0
	---help---
		This the space (in rows) between each row of test.  Default: 0

config NXCONSOLE_NOWRAP
	bool "No wrap"
	default n
	---help---
		By default, lines will wrap when the test reaches the right hand side
		of the window. This setting can be defining to change this behavior so
		that the text is simply truncated until a new line is  encountered.

commont "NxConsole Input options"

config NXCONSOLE_NXKBDIN
	bool "NX KBD input"
	default n
	---help---
		Take input from the NX keyboard input callback.  By default, keyboard
		input is taken from stdin (/dev/console).  If this option is set, then
		the interface nxcon_kdbin() is enabled.  That interface may be driven
		by window callback functions so that keyboard input *only* goes to the
		top window.

config NXCONSOLE_KBDBUFSIZE
	int "Keyboard Input Buffer Size"
	default 16
	---help---
		If NXCONSOLE_NXKBDIN is enabled, then this value may be used to
		define the size of the per-window keyboard input buffer.  Default: 16

config NXCONSOLE_NPOLLWAITERS
	int "Number of Poll Waiters"
	default 4
	---help---
		The number of threads that can be waiting for read data available.
		Default: 4

config NX_MXSERVERMSGS
	int "Max Server Messages"
	default 32
	---help---
		Specifies the maximum number of messages that can fit in the message queues.
		No additional resources are allocated, but this can be set to prevent
		flooding of the client or server with too many messages (PREALLOC_MQ_MSGS
		controls how many messages are pre-allocated).

config NX_MXCLIENTMSGS
	int "Max Client Messages"
	default 16
	---help---
		Specifies the maximum number of messages that can fit in the message queues.
		No additional resources are allocated, but this can be set to prevent
