-------------------------------------------------------------------------------

20091231
	add test-screens for setting/querying xterm fonts.

	improve display for 94-item character set tests by assuming that
	DEL would be ignored, and writing a blank after it rather than
	allowing a ')' to be mapped in the selected character set.

	check whether terminal is vt220 or vt320 to decide which Latin-1
	flavor to use for initializing the character set tests.

	miscellaneous fixes for configure script macros.

	updated config.guess, config.sub

20071216
	modify VT420 rectangle tests to provide ANSI/ISO colors and
	line-drawing as test-options.

	miscellaneous updates to configure script macros.

	updated config.guess, config.sub
	
20070304
	build-fix for Darwin 8.8 or OS X 10.4.x, (report by David Blanchard).

20070107
	contacted Per Lindberg (2007/1/2), received permission to change his
	copyright notice to a BSD-style license.

20061126
	add screen to DECCRA test to demonstrate if video attributes are
	copied along with the window, or supplied from the current attributes.

	use CF_XOPEN_SOURCE in configure script to get prototype for usleep()
	on Linux.

	updated config.guess, config.sub

20051020
	add suffix information to configure script to work with cygwin, etc.

	modify window-reporting operations to handle result strings that may be
	longer than a single line.

	improve configure script checks for Intel compiler warning options.

	add "%u" format needed in va_out() to work with 20050107 change
	to mouse-highlight test.

20050107
	improve test for vt220 locking shifts, showing GL/GR side-by-side to
	demonstrate which are modified.

	add logging for text which is part of test-screens

20041220
	modify configure script to work with Intel compiler.

	improved parameterization of scrolling test for screen sizes other
	than 24x80.

	add initialization to disable tab/space conversion during menu items
	1 and 2, e.g., when "stty tab3" is set (report by Pavel Cahyna).

20041205
	add the ability to redraw the screen for mouse-tests, since some can
	produce lots of output, e.g., the any-event tracking.

	modify function which reads replies, e.g., from DA, to retry as long
	as it has read data.  This is needed for connecting to real VTxxx
	terminals vs emulators (report by Pavel Cahyna).

20041107
	modify lib$wait() call to work on IA64, which uses a different default
	float format than VAX and Alpha.

	update vmsbuild.com and descrip.mms to build on IA64.

	fix typo in vmsbuild.com

20040804
	change parameter for ioctl(fd, FIONREAD, &param) to an int.

	add a test screen for BCE color behavior with ECH, DCH and scrolling.

	add a demo of some of the VT100 autowrap behavior to menu 1.

	add xterm's control sequence to disable reverse wraparound to the
	initialization (this would conflict with DECGPCS if that were tested,
	but eliminates some user confusion in menu-1).

	add entries for VT520/VT525 DA2 responses.

	decode DA1 response for VT125.

	add note in REP test regarding undefined behavior from using two
	REP controls in a row (report by Brian Pence).

	change SPA test to allow setting/unsetting ERM while running it
	(request by Brian Pence).

	add VT420, VT520 entries to table for DECRPM test, and split that
	into VT320- and VT420-only tests.

	add VT520 entries to character-set and keyboard dialect tables.

	correct cleanup from menu 3 (see 990120), which left G1-G3 set to
	tested character sets rather than resetting to ASCII.

	split-out vt320.c, modifying VT220- and VT420-menus to avoid
	most duplication by pointing to lower-level terminals in the menu.

	correct message from check_rc() in xterm.c (report by Brian Pence).

	add --disable-echo option to configure script

	update configure script.

20030301
	add tek4014 test menu, for xterm.

20021208
	improved test for cursor-control sequences within escape sequences
	(patch by Paul Williams).

20020422
	modify keyboard tests for cursor- and keypad-application modes to
	reset the keyboard back to normal mode at the end of each test
	(reported by Takashi SHIRAI <shirai@nintendo.co.jp>).

	modify test-screen for DEC locator events to add a function that checks
	for the screensize, used for XFree86 xterm to scale the pixel reports.

	updates to configure script and makefile:  omit dependencies on
	config.status and improve list of gcc warning options.

20011130
	add tests for xterm alternate screen

	split-out xterm mouse tests into mouse.c menu.

20000208
	change coding of wheel-mouse events, XFree86 xterm patch #126.

991228
	modify to report wheel-mouse events for XFree86 xterm (patch #122).

991025
	clarify top-level reports menu, which mixes tests that apply to various
	models (VT100-VT420).

	show decoded modifiers for the xterm mouse tests

991014
	modify position of cursor for printer tests, so autoprint tests work
	as expected.

	correct escape sequence for mc_print_page().

991007
	implement tests for Media Copy, e.g., transparent printing.

	add examples for DEC locator events and DSR responses.

	add DA responses for VT50 and VT55 (I'd forgotten that I once bought a
	DECscope booklet).

990712
	modify menu 3.12 (non-VT100 "Test Keyboard Layout with G0 Selection")
	to show numeric codes as well as the actual character.

	remove spurious test for SD which indicated that ISO's coding differed
	from DEC's.  The difference was a typographical error in ECMA-48
	(reported by Paul Williams <paul@celigne.co.uk>).

990120
	correct initialization of G0, for character-set shift-in/shift-out test.

	change keyboard layout screen so that, when invoked from the character
	set menu, it will display NRC characters properly.

	correct logic of reset_charset() function, which used the wrong index
	for do_scs() (reported by Jeffrey Altman).

	set/restore character set for keyboard layout test in character-set
	menu.

990119
	add menu entry for enabling NRC mode, and (for VT220 & up) a menu
	entry to allow testing keyboard layout with NRC mode enabled.

	remove logic that sets NRC mode from setup for character-set tests,
	since that interferes with new menu entry.

	change delimiting characters for single-shift test screen from "{" and
	"}" to "(" and ")" to avoid confusion (the DECterm program which I have
	tested with maps the curly braces even in an unshifted state according
	to the state of the NRC mode).

	reset character-set of G0 after tst_vt100_charsets

	restore terminal modes after answerback test.

980719
	add tests to illustrate any-event and button-event tracking in XFree86
	xterm.

980328
	add logic to ensure we pick up the proper choice (e.g., in Norwegian)
	where the choice depends on the terminal id (e.g., VT220 vs VT320).

	minor correction for VT220 vs VT320 logic in do_scs for Latin-1 vs
	British character set.

980327
	implement test for single-shift (SS2 and SS3).

980326
	implement shift-in/shift-out character-set tests oriented toward VT220.

	several corrections to VT220 character-set tests, from reports by
	Kenneth R. Robinette <zkrr01@mailbox.neosoft.com>:

		+ move SCS strings to immediately before/after the tests to
		  avoid conflict with menu selection, and to keep the tests
		  distinct.

		+ use 96-character control sequences only for character sets
		  (Latin 1), and 94-character control sequences for the
		  National Replacement character sets.

		+ add ISO Latin-1 as a font option

		+ add Swiss as a font option

980310
	decode known values for secondary DA response.

	make mouse-highlight test a little clearer by putting '+' marks at the
	corners of the highlight-region.

970524
	eliminate 'gets()' calls, which can overflow buffer.

970520
	implement CF_FCNTL_VS_IOCTL check to make this build on SCO 3.x and
	CLIX, which are both non-POSIX systems.

970518
	add CF_POSIX_VDISABLE test to work around gcc 2.6.2 bug.

970419
	correct sign-extension in xterm mouse-position

961215
	correct err introduced between d960905 and v2_5 that broke test for IRM
	mode by using decsclm (reported by Jeffrey Altman).

961125
	add VT220 character-set tests for locking-shifts

961028
	implemented tests for VT220/VT420 function keys, editing keypad.

961027
	change suggested by Jeffrey Altman:  set the terminal's default
	operating level to the maximum rather than VT100 (this is slightly
	incompatible with VTTEST 1.7).

960928
	allow 8-bit input for keyboard (function keys, cursor keys) tests.

	Jeffrey Altman).

	Corrected test for DECRPM, missing '?' (reported by Jeffrey Altman
	<jaltman@watsun.cc.columbia.edu>).

VERSION 2.5

960818
	implements most VT420 report-tests.

	make menu-skeleton for VT420 tests (some are needed for xterm tests),
	marking the non-implemented entries with an '*'.

	add tests/examples for xterm mouse controls

960816
	remove obsolete support for Sargasso C (TOPS-20)

960813

	add menu-entry for toggling 7/8-bit input/output controls

	split-out keyboard.c, organized by a set of submenus.

	split-out reports.c, parameterized to allow testing 8-bit controls.
	make submenu for individual reports.

	modified menu decoding to accept '*' to step through all submenus.

VERSION 2.4

960807
	Implement test for VT5xx C7C1T and S8C1T

	Remove check for scrolling-behavior in CPL and CNL (no one but kermit
	seems to consider doing this).

	Modified tst_reports() to use raw mode (the original sgtty logic
	doesn't do this) so that termios works.  Modified termios settings for
	crmod so it doesn't touch INLCR and IGNCR, and for raw mode to leave
	c_oflag alone - this works on Linux.

	corrected some typos in DECSCA test.

960806
	Testing by Albert D. Cahalan <acahalan@cs.uml.edu> with VT510,
	suggested initializing with the 80/132 mode enabled.  Says real
	terminals need padding...

960802
	Restructure non-VT100 menus, making them separate from the base VT100
	tests.

VERSION 2.2

960721
	Initialize terminal with 80/132 switching enabled

	Casper Dik <casper@holland.Sun.COM> explained why tests fail on Solaris
	2.5 (can workaround with lots of fflush calls ;-)

960716
	Add tests for CDE-compatible xterm

VERSION 2.1

960708
	Change background color to blue for tests (some yellows and greens
	are too close together).

	Added extended graphic-rendition tests (ISO 6429)

VERSION 2.0

960624
	Added color/graphic-rendition, and color-scrolling tests.

960623
	Implemented color tests (test-pattern, bce-test, insert/delete lines)

960621
	Implemented auto-config for termios (tested on SunOS 4.1.1, IRIX 5.2,
	Solaris 5.4).

960618
	Modified to support nonstandard screen geometry.  For example, you can
	test Linux console (which has 25 lines) by typing 'vttest 25'.

	Implemented auto-config for termio (tested on SunOS 4.1.1).

960617
	Corrected broken write-to-string-constant in tst_keyboard().

	Split-out logic for ttymodes.c

	Converted to ANSI C (it's a lot easier to avoid breaking code when all
	of the interfaces are fully specified).

	Split-out sargasso.h from header.h, to avoid nested-comment syntax.  (I
	don't think anyone will be using that again, anyway).

	from original version (I've found nothing more recent ;-), marked 1.7b
	1985-04-19, begin making changes to support testing for ANSI color
	features.
