NAME
x3270 - IBM host access tool
SYNOPSIS
x3270 [options] [host]
DESCRIPTION
x3270 opens a telnet connection to an IBM host in an X window. It implements RFCs 2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selec- tion), and supports IND$FILE file transfer. The window created by x3270 can use its own font for displaying characters, so it is a fairly accurate representation of an IBM 3278 or 3279. It is similar to tn3270(1) except that it is X-based, not curses-based. The full syntax for host is: [prefix:]...[LUname@]hostname[:port] Prepending a p: onto hostname causes the connection to go through the telnet-passthru service rather than directly to the host. See PASSTHRU below. Prepending an s: onto hostname removes the "extended data stream" option reported to the host. See -tn below for further information. Prepending an n: onto hostname turns off TN3270E support for the session. A specific LU name to use may be specified by prepending it to the hostname with an `@'. Multiple LU names to try can be separated by com- mas. An empty LU can be placed in the list with an extra comma. On systems that support the forkpty library call, the hostname may be replaced with -e and a command string. This will cause x3270 to con- nect to a local child process, such as a shell. The port to connect to defaults to telnet. This can be overridden with the -port option, or by appending a port to the hostname with a colon `:'. (For compatability with previous versions of x3270 and with tn3270(1), the port may also be specified as a second, separate argument.)
OPTIONS
x3270 is a toolkit based program, so it understands standard Xt options and resources. It also understands the following options: -activeicon Specifies that the icon should be a miniature version of the screen image. See ICONS below. -apl Sets up APL mode. This is actually an abbreviation for several options. See APL SUPPORT below. -cc range:value[,...] Sets character classes. See CHARACTER CLASSES, below. -charset name Specifies an EBCDIC host character set. See CHARACTER SETS below. -clear toggle Sets the initial value of toggle to false. The list of toggle names is under MENUS below. -efont name Specifies a font for the emulator window. See FONTS below. -iconname name Specifies an alternate title for the program icon. -iconx x Specifies the initial x coordinate for the program icon. -icony y Specifies the initial y coordinate for the program icon. -keymap name Specifies a keymap name and optional modifiers. See KEYMAPS below. -keypad Turns on the keypad as soon as x3270 starts. -model name The model of 3270 display to be emulated. The model name is in two parts, either of which may be omitted: The first part is the base model, which is either 3278 or 3279. 3278 specifies a monochrome 3270 display; 3279 specifies a color 3270 display. When 3278 emulation is specified for a color X display, fields are displayed using pseudo-colors; see PSEUDO-COLOR below. The second part is the model number, which specifies the number of rows and columns. Model 4 is the default. Model Number Columns Rows ------------------------------ 2 80 24 3 80 30 4 80 43 5 132 27 Note: Technically, there is no such 3270 display as a 3279-4 or 3279-5, but most hosts seem to work with them anyway. The default model for a color X display is 3279-4. For a monochrome X display, it is 3278-4. (The behavior of early versions of x3270 on color X displays can be specified as 3278-4). -mono Forces x3270 to believe it is running on a monochrome X display. -once Causes x3270 to exit after a host disconnects. This option has effect only if a hostname is specified on the command line. -oversize colsxrows Makes the screen larger than the default for the chosen model number. This option has effect only in combination with extended data stream support (controlled by the "x3270.extended" resource), and only if the host supports the Query Reply structured field. The number of columns multiplied by the number of rows must not exceed 16383 (3fff hex), the limit of 14-bit 3270 buffer addressing. -port n Specifies a different TCP port to connect to. n can be a name from /etc/services like telnet, or a number. This option changes the default port number used for all connections. (The positional parameter affects only the initial connection.) -printerlu luname Causes x3270 to automatically start a pr3287 printer session. If luname is ".", then the printer session will be associated with the interactive terminal session (this requires that the host support TN3270E). Otherwise, the value is used as the explicit LU name to associate with the printer session. -reconnect Causes x3270 to automatically reconnect to the host if it ever disconnects. This option has effect only if a hostname is specified on the command line. -sb Turns on the scrollbar. +sb Turns the scrollbar off. -scheme name Specifes a color scheme to use in 3279 mode. This option has effect only in combination with 3279 emulation. See COLOR SCHEMES below. -script Causes x3270 to read commands from standard input, with the results written to standard output. The protocol for these commands is documented in x3270-script(1). -sl n Specifies that n lines should be saved for scrolling back. The default is 64. -set toggle Sets the initial value of toggle to true. The list of toggle names is under MENUS below. -tn name Specifies the terminal name to be transmitted over the telnet connection. The default name is IBM-model_name-E, for example, IBM-3279-4-E for a color X display, or IBM-3278-4-E for a monochrome X display. Some hosts are confused by the -E suffix on the terminal name, and will ignore the extra screen area on models 3, 4 and 5. Prepending an :s on the hostname, or setting the "x3270.extended" resource to "false", removes the -E from the terminal name when connecting to such hosts. The name can also be specified with the "x3270.termName" resource. -trace Turns on data stream tracing at startup. Unlike turning it on from a menu option, there is no pop-up to confirm the file name, which defaults to /tmp/x3trc.process_id. -tracefile file Specifies a file to save data stream and event traces into, overriding the default of /tmp/x3trc.process_id. If the value stdout is given, then traces will be written to standard output. If the value none is given, then traces will be piped directly to the monitor window, and no file will be created. -tracefilesize size Places a limit on the size of a trace file. If this option is not specified, or is specified as 0 or none, the trace file will be unlimited. If specified, the trace file cannot already exist, and the (silently enforced) minimum size is 64 Kbytes. The value of size can have a K or M suffix, indicating kilobytes or megabytes respectively. After reading resource definitions from the X server and any standandard X11 resource definition files ($HOME/.Xdefaults, etc.), x3270 will read definitions from the file $HOME/.x3270pro. This file contains local customizations and is also used to save changed options by the Save Changed Options in File menu option. Note that -xrm options override any definitions in the .x3270pro file.
FONTS
x3270 does not use the "*font" resource for its main window. Instead, it uses a custom 14-point font called 3270, which is a close approximation of a real 3270 display and allows x3270 to display the ISO 8859-1 (Latin-1) character set and special status-line symbols. A more compact font, 3270-12, is also supported, as are the various sized fonts 3270gt8, 3270gt12, 3270gt16, 3270-20, 3270gt24, and 3270gt32. The fonts 3270h and 3270gr are also included to allow display of Hebrew and Greek text, respectively. The font may be specified with the -efont option or the "x3270.emulatorFont" resource. x3270 can also use any X11 font that implements the display character set required by the host EBCDIC character set. An additional font, 3270d, is supplied. This font is identical to the default 3270 font, except that it has bitmaps defined for field attribute characters. This means that field attributes, which are normally displayed as blanks, are now visible on the screen. The characters displayed are hexadecimal codes, which can be translated using a document provided with the x3270 sources. The font can be changed at any time through a menu option. It can also be implicitly changed by changing the size of the x3270 window with the mouse: if the window is made larger, x3270 will try to change to a larger font, and vice-versa.
CHARACTER SETS
The -charset option or the "x3270.charset" resource controls the EBCDIC host character set used by x3270. Available sets include: Charset Name Code Page Display Character Sets -------------------------------------------------------- apl 37 3270cg-1a belgian 500 3270cg-1a 3270-cg1 iso8859-1 bracket 37 3270cg-1a 3270-cg1 iso8859-1 brazilian 275 3270cg-1a 3270-cg1 iso8859-1 finnish 278 3270cg-1a 3270-cg1 iso8859-1 french 297 3270cg-1a 3270-cg1 iso8859-1 german 273 3270cg-1a 3270-cg1 iso8859-1 greek 423 3270cg-7 hebrew 424 3270cg-8 icelandic 871 3270cg-1a 3270-cg1 iso8859-1 iso-hebrew 424 iso8859-8 iso-turkish 1026 iso8859-9 italian 280 3270cg-1a 3270-cg1 iso8859-1 norwegian 277 3270cg-1a 3270-cg1 iso8859-1 russian 880 koi8-r solvenian 870 iso8859-2 thai 838 iso8859-11 tis620.2529-0 uk 285 3270cg-1a 3270-cg1 iso8859-1 us-intl 37 3270cg-1a 3270-cg1 iso8859-1 The default character set is bracket, which is useful for common IBM hosts which use EBCDIC codes 0xAD and 0xBD for the `[' and `]' characters, respectively. Most 3270 fonts implement the 3270cg-1 display character set, which is a reordered version of the ISO 8859-1 character set. Some implement the 3270cg-1a display character set, which is a superset of 3270cg-1 that includes APL2 characters. 3270h and 3270gr implement special character sets for Hebrew and Greek, respectively. You can also specify national-language translations for your keyboard; see KEYMAPS below.
CHARACTER CLASSES
x3270 supports character classes (groupings of characters chosen with a double mouse click) in the same manner as xterm(1). The "x3270.charClass" resource or the -cc option can be used to alter the character class table. The default table is the same as xterm's; It groups letters together, and puts most punctuation characters in individual classes. To put all non-whitespace characters together in the same class (and duplicate the behavior of some early versions of x3270, use the following value: 33-127:48,161-255:48 See xterm(1) for further syntax details.
KEYPAD
A keypad may optionally be displayed, with a mouse-clickable button for each 3270 function key (these functions are also available from the keyboard). The keypad can be turned on and off by clicking on the "keypad" button in the upper-right-hand corner of the window. The "x3270.keypad" resource controls where it is displayed. Options are: left in a separate window, to the left of the screen right in a separate window, to the right of the screen bottom in a separate window, below the screen integral in the same window as the screen, below it The default is right. If the "x3270.keypadOn" resource is set to true, the keypad will be displayed at startup.
HOSTS DATABASE
x3270 uses the ibm_hosts database to construct a pull-down menu of hosts to connect to. It also allows host name aliases to be defined, as well as specifying macros to be executed when a connection is first made. See ibm_hosts(5) for details. You may specify a different ibm_hosts database with the "x3270.hostsFile" resource.
COLOR SCHEMES
When emulating a 3279 display, the X colors used to draw the display are selected by two resources: the "x3270.colorScheme" resource, which gives the name of the color scheme to use, and the individual "x3270.colorScheme.xxx" resources, which give the actual definitions. The color scheme resources are documented in the Resources file with the x3270 source. The color scheme may also be changed while x3270 is running with a selection from the Options menu. PSEUDO-COLOR When emulating a 3278 display on a color X display, x3270 does not understand IBM 3270 color protocols. Instead, it draws text in one of three colors depending on the field attributes. Those colors may be customized using the following resources (shown with their default values): x3270.normalColor: green x3270.boldColor: cyan x3270.inputColor: orange x3270.colorBackground: black x3270.selectBackground: dim gray NVT (ANSI) MODE Some hosts use an ASCII front-end to do initial login negotiation, then later switch to 3270 mode. x3270 will emulate an ANSI X.64 terminal until the host places it in 3270 mode (telnet BINARY and SEND EOR modes, or TN3270E mode negotiation). The emulation is fairly complete; however, it is not intended to make x3270 a replacement for xterm(1). If the host later negotiates to stop functioning in 3270 mode, x3270 will return to ANSI emulation. In NVT mode, x3270 supports both character-at-a-time mode and line mode operation. You may select the mode with a menu option. When in line mode, the special characters and operational characteristics are defined by resources: Mode/Character Resource Default -------------------------------------------------------- Translate CR to NL x3270.icrnl true Translate NL to CR x3270.inlcr false Erase previous character x3270.erase ^? Erase entire line x3270.kill ^U Erase previous word x3270.werase ^W Redisplay line x3270.rprnt ^R Ignore special meaning of next x3270.lnext ^V character Interrupt x3270.intr ^C Quit x3270.quit ^\ End of file x3270.eof ^D Separate keymaps can be defined for use only when x3270 is in 3270 mode or NVT mode. See KEYMAPS for details.
MENUS
x3270 has a menu bar with three pull-down menus (File, Options, and Connect) and a button to turn the keypad on and off. The pull-down menus are also available as pop-up menus by using the "Ctrl" key and the left, middle and right mouse buttons, respectively. The menu bar can be turned off by setting the "x3270.menuBar" resource to false. Many sections of the File and Options menus are toggles, options that may be either on or off. The entries under the File menu are as follows: File Transfer Initiates transferring a file between the IBM host and the local workstation, using the IND$FILE protocol. A pop-up menu allows specifying the file names and other attributes of the transfer. The IND$FILE program must be installed on the IBM host, and the 3270 cursor must be located in a field that will accept a TSO or VM/CMS command. Printer Session Starts or stops a printer session. Trace Data Stream If set, network traffic (both a hexadecimal representation and its interpretation) are logged to the file /tmp/x3trc.process_id, and a window is popped up to monitor the data. The file name is confirmed with a pop-up; the default directory name for the trace file can be changed with the "x3270.traceDir" resource. Trace Keyboard/Mouse Events If set, information about keyboard and mouse events and the actions that x3270 takes in response are logged to a file. This is the same file as used for tracing the data stream, above. Event tracing is useful for creating and debugging custom keymaps, macros and scripts. For example, it will tell you precisely what action was taken in response to pressing a particular key. If the key is not mapped, it will tell you the keysym name and keycode so you can add it to a custom keymap. Save Screen(s) in File If set, saves an ASCII representation of the current screen image in the file /tmp/x3scr.process_id. A pop-up allows the file name to be changed; the default directory name can be changed with the "x3270.traceDir" resource. The pop-up also has buttons to choose between saving just the current image, or continuously saving it as it is redrawn. Save Changed Options in File Saves into a file the values of all options that have been changed since x3270 was started. A pop-up allows the file name to be changed; the default file is .x3270pro in the user's home directory. If the file already exists, it is appended to. x3270 will read the contents of this file the next time it starts up. The options settings in the file override any resources defined with xrdb or in the user's .Xdefaults file; command-line switches override the file. A different options file can be specified by the X3270PRO environment variable. If the environment variable NOX3270PRO is set, no options file will be read. Execute an Action Allows an action name and parameters to be entered from the keyboard. This allows experimentation with actions without having to edit keymaps and repeatedly restart x3270. The toggles under the Options menu are as follows: Monocase If set, x3270 operates in uppercase-only mode. Blinking Cursor If set, the cursor blinks once per second. Blank Fill If set, x3270 behaves in some un-3270-like ways. First, when a character is typed into a field, all nulls in the field to the left of that character are changed to blanks. This eliminates a common 3270 data-entry surprise. Second, in insert mode, trailing blanks in a field are treated like nulls, eliminating the annoying `lock-up' that often occurs when inserting into an field with (apparent) space at the end. Show Timing If set, the time taken by the host to process an AID is displayed on the status line. Track Cursor If set, the cursor position is displayed on the status line. Scrollbar If set, the scrollbar appears. Wraparound If set, the ANSI terminal emulator automatically assumes a NEWLINE character when it reaches the end of a line. Paste with Left Margin If set, puts restrictions on how pasted text is placed on the screen. The position of the cursor at the time the paste operation is begun is used as a left margin. No pasted text will fill any area of the screen to the left of that position. This option is useful for pasting into certain IBM editors that use the left side of the screen for control information. Select by Rectangles If set, x3270 will always select rectangular areas of the screen. Otherwise, x3270 selects by rectangles when in 3270 mode, but in ANSI mode it selects continuous regions of the screen like xterm(1). Crosshair Cursor If set, x3270 will display a crosshair over the cursor: lines extending the full width and height of the screen, centered over the cursor position. This makes locating the cursor on the screen much easier. The names of the toggles for use with the -set and -clear options are as follows: Menu Option Name ---------------------------------------------- Monocase monoCase Blinking Cursor cursorBlink Blank Fill blankFill Show Timing showTiming Track Cursor cursorPos Trace Data Stream dsTrace Trace Keyboard/Mouse Events eventTrace Save Screen(s) in File screenTrace Scrollbar scrollBar Wraparound lineWrap Paste with Left Margin marginedPaste Select by Rectangles rectangleSelect Crosshair Cursor crosshair In addition, the toggle altCursor can be used to select the cursor type. If set, an underline cursor will be used. If clear, the normal block cursor will be used. These names also represent resources that can be set in your .Xdefaults or .x3270pro file. For example, if you always want to have the scrollbar on, you can add the following to your .Xdefaults or .x3270pro: x3270.scrollBar: true These names are also used as the first parameter to the Toggle action.
STATUS LINE
The x3270 status line contains a variety of information. From left to right, the fields are: comm status Three symbols indicate the state of the connection to the host. If connected, the right-hand symbol is a solid box; if not, it is a question mark. keyboard lock If the keyboard is locked, an "X" symbol and a message field indicate the reason for the keyboard lock. shift Three characters indicate the keyboard modifier status. "M" indicates the Meta key, "A" the Alt key, and an up-arrow or "^" indicates the Shift key. compose The letter "C" indicates that a composite character is in progress. If another symbol follows the "C", it is the first character of the composite. typeahead The letter "T" indicates that one or more keystrokes are in the typeahead buffer. temporary keymap The letter "K" indicates that a temporary keymap is in effect. reverse The letter "R" indicates that the keyboard is in reverse field entry mode. insert mode A thick caret "^" or the letter "I" indicates that the keyboard is in insert mode. printer session The letter "P" indicates that a pr3287 session is active. script The letter "S" indicates that a script is active. LU name The LU name associated with the session, if there is one. timing A clock symbol and a time in seconds indicate the time it took to process the last AID or the time to connect to a host. This display is optional. cursor position The cursor row and column are optionally displayed, separated by a "/".
ICONS
If the -activeicon option is given (or the "x3270.activeIcon" resource is set to true), x3270 will attempt to make its icon a miniature version of the current screen image. This function is highly dependent on your window manager: mwm The size of the icon is limited by the "Mwm.iconImageMaximum" resource, which defaults to 50x50. The image will be clipped at the bottom and right. The icon cannot accept keyboard input. olwm The full screen image of all 3270 models can be displayed on the icon. However, the icon cannot be resized, so if the model is later changed with an x3270 menu option, the icon image will be corrupted. The icon cannot accept keyboard input. twm and tvtwm The full screen image of all 3270 models can be displayed on the icon, and the icon can be resized. The icon can accept keyboard input. However, twm does not put labels on application-supplied icon windows. You can have x3270 add its own label to the icon by setting the "x3270.labelIcon" resource to true. The default font for icon labels is 8x13; you may change it with the "x3270.iconLabelFont" resource.
KEYMAPS
The type of keyboard may be specified with the -keymap switch or using either the KEYMAP or KEYBD environment variables. The types of supported keyboards include sun_k3, sun_k4, sun_k5, hp-k1, hp-pc and ncd. The keymap may also be specified as a comma-separated list of names. Later definitions override earlier ones. This is used to specify both a primary keyboard type and a set of modifiers. The modifiers defined include: ow (OpenWindows) Swaps the middle and right mouse button definitions, so the middle button performs the "Extend" function and the right-hand button performs the "Paste" function. Also changes the cut and paste actions to use the OpenWindows CLIPBOARD. alt Replaces the default "Meta" key definitions with "Alt" definitions, for keyboards which do not have a "Meta" key. apl Allows entry of APL characters (see APL SUPPORT below). finnish7 Replaces the bracket, brace and bar keys with common Finnish characters. norwegian7 Replaces the bracket, brace and bar keys with common Norwegian characters. A temporary keymap can also be specified while x3270 is running with the Keymap action. When the action Keymap(n) is executed, temporary keymap n is added to or deleted from the current keymap. Multiple temporary keymaps can be active simultaneously. The action Keymap(None) restores the original keymap. Note: When Keymap() is specified as part of a list of multiple actions in a keymap, it must be the last action in the list. The temporary keymap hebrew is provided to allow entry of Hebrew characters. The X Toolkit translation mechanism is used to provide keyboard emulation. It maps events into actions. The best documentation can be found with X toolkit documents, but the following should suffice for simple customization. An Xt event consists of (at least) four fields. The first is called a modifier. It may be any combination of Meta, Shift and Ctrl. If it is prefaced by !, it means those modifiers only. The second field is the specific event, in x3270 usually just <Key>. The third field is the detail field, which gives the actual key. The name of the key may be determined using the xev program or with the "Trace X Events" menu option. The last field is the action, which is the internal emulator function. A complete list of actions may be found later in the manual. There are three levels of translation tables in x3270. The first is a defined by the resource x3270.keymap.base. It defines alphabetic, numeric, function keys, and such basic functions as Enter and Delete. It allows a minimal useful functionality. It is generally compiled in x3270, but can be overridden. The second level is a keyboard specific table, which is selected by the x3270.keymap resource, and defined by the x3270.keymap.name resource (where name is the value of the x3270.keymap resource). This keymap defines actions for such things as keypad keys, and keys unique to certain keyboards. Several predefined keymaps are included with x3270. The third level is a user customizable table which may be used to augment or override key definitions. This keymap is defined by the x3270.keymap.name.user resource. In addition, keymaps may be defined for use in 3270 mode or NVT mode only. These keymaps use the suffixes .3270 and .nvt in their names, respectively. If a keymap x3270.keymap.name.mode is defined, it will augment the keymap x3270.keymap.name when x3270 is in the given mode. If a keymap x3270.keymap.name.user.mode is defined, it will augment the keymap x3270.keymap.name.user when x3270 is in the given mode. The default translation table x3270.keymap.base is: <Key>Multi_key Compose() Shift<Key>Left KybdSelect(Left,PRIMARY) <Key>Left Left() Meta<Key>Right NextWord() Shift<Key>Right KybdSelect(Right,PRIMARY) <Key>Right Right() Shift<Key>Up KybdSelect(Up,PRIMARY) <Key>Up Up() Shift<Key>Down KybdSelect(Down,PRIMARY) <Key>Down Down() Ctrl<Btn1Down> HandleMenu(quitMenu) Ctrl<Btn2Down> HandleMenu(optionsMenu) Ctrl<Btn3Down> HandleMenu(hostMenu) Shift<Btn1Down> MoveCursor() <Btn1Down> select-start() <Btn1Motion> select-extend() <Btn2Down> ignore() <Btn2Motion> ignore() <Btn2Up> insert-selection(PRIMARY) <Btn3Down> start-extend() <Btn3Motion> select-extend() <BtnUp> select-end(PRIMARY) Meta<Key>F1 PF(13) Meta<Key>F2 PF(14) Meta<Key>F3 PF(15) Meta<Key>F4 PF(16) Meta<Key>F5 PF(17) Meta<Key>F6 PF(18) Meta<Key>F7 PF(19) Meta<Key>F8 PF(20) Meta<Key>F9 PF(21) Meta<Key>F10 PF(22) Meta<Key>F11 PF(23) Meta<Key>F12 PF(24) <Key>F1 PF(1) <Key>F2 PF(2) <Key>F3 PF(3) <Key>F4 PF(4) <Key>F5 PF(5) <Key>F6 PF(6) <Key>F7 PF(7) <Key>F8 PF(8) <Key>F9 PF(9) <Key>F10 PF(10) <Key>F11 PF(11) <Key>F12 PF(12) Alt<Key>q Quit() :<Key> Default() The default 3270-mode table x3270.keymap.base.3270 adds the following definitions: Shift<Key>Return Newline() <Key>Return Enter() <Key>Linefeed Newline() Shift<Key>Tab BackTab() <Key>Tab Tab() <Key>Home Home() Meta<Key>Left PreviousWord() Meta<Key>Right NextWord() <Key>Insert Insert() <Key>Delete Delete() <Key>BackSpace BackSpace() Ctrl Shift<Btn1Down> MouseSelect() Shift<Btn1Down> MoveCursor() Meta<Key>1 PA(1) Meta<Key>2 PA(2) Meta<Key>3 PA(3) Meta<Key>a Attn() Meta<Key>b PrintWindow() Meta<Key>c Clear() Meta<Key>d Delete() Meta<Key>h Home() Meta<Key>i Insert() Meta<Key>l Redraw() Meta<Key>p PrintText() Meta<Key>r Reset() Meta<Key>u Unselect() Ctrl<Key>u DeleteField() Ctrl<Key>w DeleteWord() :Meta<Key>asciicircum Key(notsign) Meta is the diamond shaped key on a sun_k4, "Alt" on an NCD, "Extend Char" on an HP. The following xmodmap command must be used on the NCD to allow use the the "Alt" key: xmodmap -e "keysym Alt_L = Meta_L" The left mouse button may be used to make a selection. Clicking once unselects the current selection. Clicking twice selects the word under the mouse cursor. Clicking three times selects the line under the mouse cursor. Clicking and dragging selects a rectangular area of the display. The middle mouse button may be used to paste a selection. The right mouse button may also be used for selections, selecting the rectangular area between the current position and where the left button was last pressed. On color X displays, the "x3270.selectBackground" resource is used to distinguish the selected text from the rest of the screen. On monochrome X displays, selected text is in reverse video. (It can be distinguished from a block cursor because the block cursor covers slightly less than an entire character position on the screen.) The left mouse button, when pressed with the "Shift" key held down, moves the 3270 cursor to the where the mouse cursor is pointing. This is the complete list of keymap-callable actions. Other actions are defined for use by scripts and are documented in x3270-script(1); still others are defined for internal use by x3270 and are not documented here.

MACROS AND SCRIPTS
There are several types of macros and script functions available. The String Action The simplest method for macros is provided via the String action. The arguments to String are one or more double-quoted strings which are inserted directly as if typed. The C backslash conventions are honored as follows. (Entries marked * mean that after sending the AID code to the host, x3270 will wait for the host to unlock the keyboard before further processing the string.) \b Left \f Clear* \n Enter* \pan PA(n)* \pfnn PF(nn)* \r Newline \t Tab \T BackTab An example keymap entry would be: Meta<Key>p: String("probs clearrdr\n") Note: The strings are in ASCII and converted to EBCDIC, so beware of inserting control codes. Also, a backslash before a p may need to be doubled so it will not be removed when a resource file is read. There is also an alternate form of the String action, HexString, which is used to enter non-printing data. The argument to HexString is a string of hexadecimal digits, two per character. A leading 0x or 0X is optional. In 3270 mode, the hexadecimal data represent EBCDIC characters, which are entered into the current field. In NVT mode, the hexadecimal data represent ASCII characters, which are sent directly to the host. The Script Action This action causes x3270 to start a child process which can execute x3270 actions. Standard input and output from the child process are piped back to x3270. The Script action is fully documented in x3270-script(1). The macros Resource An alternate method of defining macros is the "x3270.macros" resource. This resource is similar to a keymap, but instead of defining keyboard mappings, it associates a list of X actions with a name. These names are displayed on a Macros menu that appears when x3270 is connected to a host. Selecting one of the names on the menu executes the X actions associated with it. Typically the actions are String calls, but any action may be specified. Here is a sample macros resource definition, which would result in a four-entry Macros menu: x3270.macros: \ log off: String("logout\n")\n\ vtam: String("dial vtam\n")\n\ pa1: PA(1)\n\ alt printer: PrintText("lpr -Plw2") You can also a different set of macros for each host. If there is a resource named `x3270.macros.somehost', it defines the macros menu for when x3270 is connected to somehost. The -script Option This facility allows x3270 to operate under the complete control of a script. x3270 accepts actions from standard input, and prints results on standard output. The -script option is fully documented in x3270-script(1).
COMPOSITE CHARACTERS
x3270 allows the direct entry of accented letters and special symbols. Pressing and releasing the "Compose" key, followed by two other keys, causes entry of the symbol combining those two keys. For example, "Compose" followed by the "C" key and the "," (comma) key, enters the "C-cedilla" symbol. A C on the status line indicates a pending composite character. The mappings between these pairs of ordinary keys and the symbols they represent is controlled by the "x3270.composeMap" resource; it gives the name of the map to use. The maps themselves are named "x3270.composeMap.name". The default is "latin1", which gives mappings for most of the symbols in the ISO 8859-1 Latin-1 character set that are not in the 7-bit ASCII character set. Note: The default keymap defines the "Multi_key" keysym as the "Compose" key. If your keyboard lacks such a key, you may set up your own "Compose" key with a keymap that maps some other keysym onto the Compose action.
APL SUPPORT
x3270 supports the full APL2 character set and the entry of APL characters from the keyboard. APL characters are supported only in the special 3270 font. Keyboard entry of APL characters is supported through the apl keymap modifier. This modifier defines the "Alt" key as an APL key, with a typical APL keyboard layout, e.g., "Alt" pressed with the A key results in the APL "alpha" symbol. Overstruck characters such as "quad- quote" are not defined as single keystrokes; instead they are entered as composites (see COMPOSITE CHARACTERS above). A special composite map, apl, is provided for this purpose. Note: Some keyboards do not the "Alt" key as a modifier, so keymaps that use the "Alt" key will not function. On a Sun for example, this can be remedied with the command: xmodmap -e "add mod2 = Alt_L" For convenience, an -apl option is defined, which is an abbreviation for the following resource definitions: x3270.keymap: your_keymap_name,apl x3270.charset: apl x3270.composeMap: apl There are a number of APL characters that are similar in appearance to non-APL characters. In particular, the APL "stile", "slope," "tilde" and "quotedot" characters are similar to the EBCDIC "bar", "backslash," "tilde" and "exclaim" characters. The APL characters are entered with the "Alt" key, and have slightly different appearances. The complete list of special APL keysyms is as follows. Entries marked with an asterisk (*) represent simple aliases for standard EBCDIC characters. Entries marked with an (S) represent Sharp APL charatcers.

This is not native 5250 terminal emulation, but rather for use with hosts which allow a 3270 terminal to emulate a 5250. A 5250 keymap is defined, which maps the keyboard function keys to the 5250 emulators PA/PF key sequences, as well as redefining the Return key to use the special FieldExit action. The command line for 5250 support is: x3270 -model 2 -keymap 5250
SCREEN PRINTING
Screen printing is handled through options on the File menu or by the PrintText and PrintWindow actions. Each results in a pop-up to confirm the print command. The PrintText action (usually assigned to the key <Meta>p) sends the current screen image to the printer as ASCII characters. The default command used to print the data is controlled by the "x3270.printTextCommand" resource; the default is lpr. You may also use a keymap definition to pass a print command the PrintText action itself. The command receives the screen text as its standard input. For example, the following keymap will save the screen text in a file: Meta<Key>f: PrintText("cat >screen.image") Note: HardPrint is an alias for PrintText. The PrintWindow action (usually assigned to the key <Meta>b) sends the current screen image to the printer as a bitmap. The default command used to print the data is controlled by the "x3270.printWindowCommand" resource; the default is xwd -id %d | xpr | lpr. You may also use a keymap definition to pass a print command to the PrintWindow action itself. If the command contains the text "%d", the window ID of x3270 will be substituted before it is run. For example, the following keymap will pop up a duplicate of the current screen image: Meta<Key>g: PrintWindow("xwd -id %d | xwud &") If the command for PrintWindow or PrintText begins with an "@" character, the initial pop-up menu to confirm the print command is not displayed and the command cannot be edited.
BUGS
Cursor highlighting will not work with if you use the NoTitleFocus option in your .twmrc file.
PASSTHRU
x3270 supports the Sun telnet-passthru service provided by the in.telnet-gw server. This allows outbound telnet connections through a firewall machine. When a p: is prepended to a hostname, x3270 acts much like the itelnet(1) command. It contacts the machine named internet-gateway at the port defined in /etc/services as telnet-passthru (which defaults to 3514). It then passes the requested hostname and port to the in.telnet-gw server.
