20140116

produce lots of output, e.g., the any-event tracking.

as it has read data. This is needed for connecting to real VTxxx
terminals vs emulators (report by Pavel Cahyna).

+ 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).

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.

reset the keyboard back to normal mode at the end of each test

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).

+ 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 Characters.
+ add ISO Latin-1 as a font option
+ add Swiss as a font option
980310
+ decode known values for secondary DA response.

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

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 '*'.
960817
+ add tests/examples for xterm mouse controls
960816
+ remove obsolete support for Sargasso C (TOPS-20)
960813
+ use usleep() if the system has it, to make responses faster.
+ 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...
960804
+ Implement tests for: SL, SD, SU, SR
+ Modified "Test of screen features with ISO 6429 SGR 22-27 codes"
to test concealed text.
VERSION 2.3
960803
+ Implement tests for the following ISO 6429 controls: CBT, CHA, CHT,
CNL, CPL, ECH, HPA, SL, SPA, SR, VPA.
+ Implement tests for DEC VT220 controls: DECSCA, DECTCEM
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).
960702
+ 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.
