1.1 root 1: VERSION X10/6.6A
2: ------- -------
3:
4: General
5: -------
6:
7: vt102 and Tektronix 4015 emulation in separate windows, each with its own
8: mode menu (control middle button).
9:
10: Switching between each mode can be done via the menus, or with escape
11: sequences:
12: vt102 -- \E[?38h --> tek
13: tek -- \E\003 --> vt102
14:
15: The windows hilite themselves when the mouse is with either window or when
16: one of these is the focus window. The windows unhilite when the mouse moves
17: out of the window and neither is the focus window. Hiliting appears as
18: windows with solid color borders and solid block cursors. Unhiliting appears
19: as windows with "grayed" borders and a rectangle cursor.
20:
21: The parser for both modes is table-driven and is much more efficient than the
22: original parsers.
23:
24: If UTMP is define in the Makefile, then each instance of xterm makes an entry
25: in /etc/utmp and thus appears with the "who" command.
26:
27: If both windows are visible and one is iconified, both disappear. Deiconifing
28: causes both to appear again.
29:
30: If the initial mode is vt102, /etc/termcap is searched, in order, for the
31: following termcaps, until one is found:
32: xterm, vt102, vt100, ansi, dumb
33: If the vt102 window happens to be 80x24, then xterms is added to the begining
34: of the list. If the initial mode is tek, the termcaps searched for are:
35: tek4015, tek4014, tek4013, tek4010, dumb
36:
37: The window size is passed to the operating system via TIOCSWINSZ (4.3) or
38: TIOCSSIZE (sun). A SIGWINCH siganl is sent if the vt102 window is resized.
39:
40: For login windows, menus are disabled until a user has successfully login.
41: (||| This isn't currently true. )
42:
43: A new menu (xterm) has been added (control left button) that gives the version
44: number. The menu allows titlebars to be displayed (see below), the windows
45: redrawn, or for various signals to be sent to the process group of the command
46: xterm is executing. The signals include SIGCONT, SIGTSTP,SIGHUP, SIGINT,
47: SIGTERM and SIGKILL.
48:
49: Titlebars for the window can be turned off with .Xdefaults
50: "xterm.TitleBar off", with command line option -tb or via the xterm menu.
51:
52: The titlebar font is, by default, vtsingle. The font can be changed with
53: .Xdefaults "xterm.TitleFont helv12b" for helv12b font or via command line
54: option -ft helv12b.
55:
56: The titlebar look like Macintosh titlebars. A series of strips appears when the
57: window is hilited, and are gone when unhilited.
58:
59: Both windows are visible and the mouse cursor is in either window, only the
60: active window is hilited (before both windows were hilited).
61:
62: Visual bell mode can be turned on via .Xdefaults "xterm.VisualBell on", via
63: command line option -vb and from the xterm menu.
64:
65: The tek window has the same name as the vt102 window, but with " (Tek)"
66: appended (before they were the same).
67:
68: There are several bug fixes including better sun compatibility and a problem
69: in the vt102 parse table.
70:
71: Xterm now always creates its own icon(s), which includes the window's name.
72: The -i option now means startup showing the icon. The option #[+-]x[+-]y
73: means to position the icon there instead of centered within the window.
74: The icon reverse-videos with the windows.
75:
76: When the mouse is in the stripped area of the titlebar, you can get any
77: of the two menus without pressing the control key. Clicking in the
78: actual title iconifies. Clicking in an icon deiconifies it.
79:
80: Many mode option on the command line allow a '+' instead of '-' to indicate
81: turning off the indicated mode.
82:
83: Color support has been improved, so that an unselected cursor is an empty
84: rectangle with the foreground color, and the selected cursor is a filled
85: rectangle with the cursor color.
86:
87: A better and faster menu package has been added that supports (Mac-like)
88: checkmarks and dimmed (disabled and grayed) item, as well as line separator
89: items.
90:
91: To conserve on resources, the unhilited border of the window(s) is now
92: always a gray pixmap, which is shared by the menu package.
93:
94: Logging capability has been added, in which all characters sent to the
95: xterm window are recorded. The mode is turned on by using .Xdefaults option
96: "xterm.Logging on", -l on the command line, from the xterm menu or the
97: escape sequence \E[?46h in vt102 mode. Logging is turned off through the
98: xterm menu or \E[?46l in vt102 mode. The default log file is XtermLog.XXXXX
99: (XXXXX is the process id of xterm) and is in the initial directory in which
100: xterm was started (the home directory for login xterms). Each logging start
101: appends to the end of the loggin file, and each logging stop closes the file.
102:
103: An alternate logging file may be given with .Xdefaults "xterm.LogFile file"
104: (file is the alternate filename) or with command line option "-lf file".
105: If the first character of the logfile name is `|', then the rest of the
106: name passed to the shell for execution and a pipe is created to the process.
107: In this case, each time the log is started, a new process is created and
108: when logging is turned off, the pipe is closed. Thus, a logfile name of
109: "| lpr", will send text to the line printer each time logging is turned off.
110:
111: Certain modes may be inhibited by specifying in the .Xdefaults file. A
112: change to the initial logging mode may be prevented with "xterm.LogInhibit on",
113: which will prevent changes to logging from the menu or from escape sequences.
114: "xterm.SignalInhibit on" disables the xterm menu signal sending (Continue is
115: still allowed). "xterm.TekInhibit on" prevents entering into Tektronix mode.
116:
117: As per edjames@eros, xterm sets the environment variable WINDOWID, which
118: contains the Window id of the initial window (normally vt102, but could be
119: the tek window if the -t option were specified). This "feature" is
120: bogus, as it may not always give you all information you need to
121: access a window.
122:
123: The title in the title bar may be changed with the \E]0;new title\007 escape
124: sequence. Any non-printing character terminates the title string. The
125: windows and icons are also renamed, and the icons are resized to fit the
126: new title.
127:
128: The log file may be changed with the \E]46;new log file\007 escape sequence.
129: If the log file name is empty, the default log file name is used.
130:
131: In visual bell mode, the icons now flash on receipt of a control-G.
132:
133: If xterm is iconified and new input comes in, a box is drawn around the
134: icon title.
135:
136: The bitmap used for the icons is now user definable. The VT102 bitmap may be
137: set with .Xdefaults "xterm.IconBitmap file" or with "-ib file" on the command
138: line. The Tek bitmap may be set with .Xdefaults "xterm.TekIconBitmap file"
139: or with "-it file" on the command line. These files are assumed to be
140: bitmap(1) format files.
141:
142: Normally, the title text of the icon is displayed to the right of the
143: bitmap. The text may be displayed under the bitmap by using .Xdefaults
144: "xterm.TextUnderIcon on" or with -ti on the command line.
145:
146: The mouse may be automatically warpped to the xterm window when it is
147: deiconified by using .Xdefaults "xterm.DeiconifyWarp on" or using -dw on
148: the command line. This is also of questionable merit.
149:
150: The standard error output used by xterm is now improved. Normally it will
151: be the same standard error when xterm is started. For login xterms
152: (-L specified) then the standard error will be to /dev/console.
153:
154: X error events are now intercepted so that xterm may cleanup before exiting
155: (like resetting the tty modes and clearing the /etc/utmp entry).
156:
157: VT102
158: -----
159:
160: vt102 emulation is much more complete than the original xterm.
161:
162: Underlined characters is now supported.
163:
164: The text for selection and extension is now hilited by reverse video.
165:
166: Pasting text that was originally displayed as vt102 graphic characters now
167: returns the original ascii character (and not the internal representation).
168:
169: Text that is scrolled off the top of the window can be saved and is accessable
170: via a scrollbar. The scrollbar is normally off, but may be made visible with
171: .Xdefault option "xterm.ScrollBar on" or command line option -sb. The
172: scrollbar state can be changed via the mode menu.
173:
174: The default maximum number of lines saved off the top is 64, but can be
175: specified in .Xdefaults as "xterm.SaveLines 100" for 100 lines, or as
176: a command line option "-sl 100".
177:
178: A margin bell can be turned on via .Xdefaults "xterm.MarginBell on", command
179: line option -mb or mode menu. The default number of columns from the right
180: margin is 10 and is settable via .Xdefaults "xterm.NMarginBell 15" for 15
181: columns, or via command line option -nb 15. The mode may be changed by escape
182: sequence \E[?44h (on) and \E[?44l (off).
183:
184: To emulate the vt102 switching between 80 and 132 columns, the mode may
185: be turned on via .Xdefaults "xterm.C132 on", via command line option -132 or
186: via the mode menu. The mode may be changed by escape sequence \E[?40h (on)
187: and \E[?40l (off).
188:
189: A mode that fixes a bug in curses (e.g. when using "more" on lines that have
190: lines that print on the last column of the line and the next line begins with
191: a tab) can be turned on .Xdefaults "xterm.Curses on", command line option
192: -cu or via the mode menu. The mode may be changed by escape sequence
193: \E[?41h (on) and \E[?41l (off).
194:
195: Auto linefeed mode and auto repeat are supported.
196:
197: The mode menu is now more descriptive.
198:
199: Most Dec Private mode settings can be save away internally using \E[?ns,
200: where n is the same number to set or reset the Dec Private mode. The
201: mode can be restored using \E[?nr. This can be used in termcap for vi, for
202: example, to turn off saving of lines, but restore whatever the original
203: state was on exit.
204:
205: An optional status line (in reverse video) has been added to the bottom of
206: the vt102 window. The following escape sequences work on the status line:
207: \E[?S show status line
208: \E[?H hide status line
209: \E[?nT enter status line, at column n
210: \E[?F return to the position before entry into status line
211: \E[?E erase status line
212: Also, the status line may be turned on via .Xdefaults "xterm.StatusLine on",
213: the -st commandline option or from the mode menu.
214:
215: Reverse wraparound can be enabled with .Xdefaults "xterm.ReverseWrap on", via
216: command line option -rw or from the mode menu. Also the escape sequences
217: \E[?45h turns on reverse wraparound and \E[?45l turns it off. Reverse
218: wraparound only works when autowrap is also on and is useful, for instance,
219: when entering a long line that wraps to the shell and needing to erase
220: backwards to correct it.
221:
222: An alternate screen buffer is now supported. Entry into the alternate screen
223: buffer with \E[?47h will automatically inhibit lines from being saved off the
224: top of the window and \E[?47l returns to the normal screen buffer and restores
225: the original state of line saving. The new termcap entry causes vi to use
226: the alternate screen buffer on entry and clears the alternate buffer before
227: returning to the regular buffer.
228:
229: If the normal font is specified and the bold font isn't, then the bold font
230: is automatically created be overstring, ala dcmartin@ingres.
231:
232: The scroll bar may be repositioned automatically at the bottom when input comes
233: in by using .Xdefaults "xterm.ScrollInput on", using -si on the command line
234: or via the scrollbar menu.
235:
236: The scroll bar may be repositioned automatically at the bottom when a key is
237: pressed by using .Xdefaults "xterm.ScrollKey on", using -sk on the command line
238: or via the scrollbar menu.
239:
240: Normally the status line is displayed in reverse video. A normal-video status
241: line may be obtained by using .Xdefaults "xterm.StatusNormal on", with
242: -sn on the command line or via the mode menu, or may be controlled with the
243: escape sequences \E[?48h (on) and \E[?48l (off). In normal video mode, a
244: box is still drawn around the status line.
245:
246:
247: Tektronix
248: ---------
249:
250: Tek mode is much more complete than the original.
251:
252: Tek standard two column mode is supported.
253:
254: Four different character sizes are supported and can be changed via the
255: tek menu.
256:
257: 5 line types are supported (solid, dotted, short dashed, long dashed and
258: dot dashed).
259:
260: All of the tek character sequences are stored and can be saved into a file
261: via the standard COPY escape sequence or from the mode menu. The file created
262: is named COPYyy-mm-dd.hh:mm:ss (COPY plus the date and time) and is placed
263: in the initial directory in which xterm was started. Login xterms use the
264: users home directory.
265:
266: When the tek window is being refreshed, the mouse cursor shows a clock.
267:
268: The X geometry of the Tek window can be given on the command line (independently
269: of the VT102 window) by using %geometry (`%' rather than `=').
270:
271: In GIN mode, pressing a key will send the key and the mouse coordinates of
272: the cross cursor, similar to standard Tek GIN mode. Pressing a mouse button
273: instead will send the character `l', `m' or `r' depending on whether the
274: left, middle or right button was pressed, respectively. If the shift key was
275: down when the button was pressed, the corresponding upper case character is
276: sent. To distinquish a button press from a key press, the high bit of the
277: character is set, but this is only useful if the tty mode is set to RAW to
278: pass all 8 bits.
