Description

[prefix:]...[LUname@]hostname[:port][=accept]

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.

Prepending an L: onto hostname causes wc3270 to first create an SSL/TLS tunnel to the host, and then create a TN3270 session inside the tunnel. (This function is supported only if wc3270 was built with SSL/TLS support). Note that TLS-encrypted sessions using the TELNET START-TLS option are negotiated with the host automatically; for these sessions the L: prefix should not be used.

Prepending a Y: onto hostname causes wc3270 to skip validation of host SSL/TLS certificates. This overrides any other configuration or command-line options.

Prepending an A: onto hostname is equivalent to setting the -nvt option; it forces an NVT-mode session instead of a 3270-mode session.

A specific Logical Unit (LU) name to use may be specified by prepending it to the hostname with an `@'. Multiple LU names to try can be separated by commas. An empty LU can be placed in the list with an extra comma. (Note that the LU name is used for different purposes by different kinds of hosts. For example, CICS uses the LU name as the Terminal ID.)

The hostname may optionally be placed inside square-bracket characters `[' and `]'. This will prevent any colon `:' characters in the hostname from being interpreted as indicating option prefixes or port numbers. This allows numeric IPv6 addresses to be used as hostnames.

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 wc3270 and with tn3270(1), the port may also be specified as a second, separate argument.)

An optional accept name (a hostname to accept in the host's SSL/TLS certificate) may be specified by appending it to the hostname with an equals sign (`='). The accept name can also be specified with the -accepthostname option.

Options

-accepthostname name

Specifies a particular hostname to accept when validating the name presented in the server SSL certificate, instead of comparing to the name used to make the connection.

-allbold

Forces all characters to be displayed using the `bold' colors (colors 8 through 15, rather than colors 0 through 7). This helps with PC console windows in which colors 0 through 7 are unreadably dim. All-bold mode is the default for color (3279) emulation, but not for monochrome (3278) emulation.

-clientcert name

Specifies the name of a client certificate to provide to the host.

-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 TOGGLES below.

-connecttimeout seconds

Specifies the time that wc3270 will wait for a host connection to complete.

-devname name

Specifies a device name (workstation ID) for RFC 4777 support.

-hostsfile file

Uses file as the hosts file, which allows aliases for host names and scripts to be executed at login. See ibm_hosts(1) for details.

-httpd [addr:]port

Specifies a port and optional address to listen on for HTTP connections. Addr can be specified as `*' to indicate 0.0.0.0; the default is 127.0.0.1. IPv6 numeric addresses must be specified inside of square brackets, e.g., [::1]:4080 to specify the IPv6 loopback address and TCP port 4080.

Note that this option is mutually-exclusive with the -scriptport option .

-loginmacro Action(arg...) ...

Specifies a macro to run at login time.

-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 (green on black) 3270 display; 3279 specifies a color 3270 display.

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	32
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 is 3279-4.

-noverifycert

For SSL/TLS connections, do not verify the host certificate.

-nvt

Start in NVT mode instead of waiting for the host to send data, and make the default terminal type xterm.

-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 "wc3270.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.

It can also be specified as auto, which causes wc3270 to fill the entire terminal or console window.

-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.)

-proxy type:host[:port]

Causes wc3270 to connect via the specified proxy, instead of using a direct connection. The host can be an IP address or hostname. The optional port can be a number or a service name. For a list of supported proxy types, see PROXY below.

-reconnect

Causes wc3270 to automatically reconnect to the host if it ever disconnects. This option has effect only if a hostname is specified on the command line.

-sl n

Specifies that n lines should be saved for scrolling back. The default is 4096.

-S

Runs wc3270 in auto-shortcut mode. wc3270 will create a temporary shorcut (.LNK file) that matches the parameters in the session file (model number, characterset, etc.) and re-run itself from the shortcut.

+S

Disables auto-shortcut mode. It is generally a good idea to put this option on the command lines of all shortcuts, to avoid infinite looping.

-scriptport [addr:]port

Specifies a port and optional address to listen on for scripting connections. Addr can be specified as `*' to indicate 0.0.0.0; the default is 127.0.0.1. IPv6 numeric addresses must be specified inside of square brackets, e.g., [::1]:4081 to specify the IPv6 loopback address and TCP port 4081.

Note that this option is mutually-exclusive with the -httpd option .

-scriptportonce

Allows wc3270 to accept only one script connection. When that connection is broken, wc3270 will exit.

-set toggle

Sets the initial value of toggle to true. The list of toggle names is under TOGGLES below. The -p option of x3270if causes it to use this socket, instead of pipes specified by environment variables.

-title text

Sets the console window title to text, overriding the automatic setting of the hostname and the string wc3270.

-tn name

Specifies the terminal name to be transmitted over the telnet connection. The default name is IBM-model_name-E, for example, IBM-3278-4-E.

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 "wc3270.extended" resource to "false", removes the -E from the terminal name when connecting to such hosts.

The name can also be specified with the "wc3270.termName" resource.

-trace

Turns on data stream and event tracing at startup. The default trace file name is x3trc.pid.txt on the current user's Desktop.

-tracefile file

Specifies a file to save data stream and event traces into. If the name starts with `>>', data will be appended to the file.

-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 size will be unlimited. The minimum size is 64 Kbytes. The value of size can have a K or M suffix, indicating kilobytes or megabytes respectively. When the trace file reaches the size limit, it will be renamed with a `-' appended and a new file started.

-user name

Specifies the user name for RFC 4777 support.

-utf8

Forces the local codeset to be UTF-8, ignoring the locale or Windows codepage.

-v

Display the version and build options for wc3270 and exit.

-verifycert

For SSL/TLS connections, verify the host certificate, and do not allow the connection to complete unless it can be validated. (This is the default setting.) This option is overridden by a y: prepended to the hostname when connecting.

-xrm "wc3270.resource: value"

Sets the value of the named resource to value. Resources control less common wc3270 options, and are defined under RESOURCES below.

Modes

Command-prompt mode is where the wc3270> prompt is displayed. Interactive commands can be entered at this prompt, to connect to a host, disconnect from a host, transfer files, display statistics, exit wc3270, etc. The complete list of interactive commands is listed under ACTIONS.

Session mode is where the emulated 3270 screen is displayed; keyboard commands cause the display buffer to be modified or data to be sent to the host.

To switch from display mode to command-prompt mode, press the Escape key. To switch from command-prompt mode to display mode, press Enter (without entering a command) at the wc3270> prompt.

The default character set is bracket, which is useful for common U.S. IBM hosts which use EBCDIC codes AD and BD for the `[' and `]' characters, respectively.

Note that any of the host code pages listed above can be specified by adding cp to the host code page, e.g., cp037 for host code page 037. Also note that the code pages available for a given version of wc3270 are displayed by the -v command-line option.

Note that DBCS character sets (Chinese, Japanese) display properly only on 32-bit Windows XP. Work is proceeding on other platforms.

Menu Bar and Keypad

The on-screen menu title bar can be turned off via the "wc3270.menuBar" resource.

The pop-up keypad allows the 3270-specific keys (PF keys, PA keys, Clear, Reset, etc.) to be invoked without memorizing their key mappings or switching to the wc3270> prompt. The keypad can be popped up by pressing Alt-K, or can be invoked via a menu option.

NVT Mode

If the host later negotiates to stop functioning in 3270 mode, wc3270 will return to NVT emulation.

In NVT mode, wc3270 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	wc3270.icrnl	true
Translate NL to CR	wc3270.inlcr	false
Erase previous character	wc3270.erase	^?
Erase entire line	wc3270.kill	^U
Erase previous word	wc3270.werase	^W
Redisplay line	wc3270.rprnt	^R
Ignore special meaning of next character	wc3270.lnext	^V
Interrupt	wc3270.intr	^C
Quit	wc3270.quit	^\
End of file	wc3270.eof	^D

Separate keymaps can be defined for use only when wc3270 is in 3270 mode or NVT mode. See KEYMAPS for details.

Toggles

aidWait

Changes the behavior of actions that send an AID to the host (Enter, Clear, PA and PF). When set, these actions no longer block until the host unlocks the keyboard. It is up to the script to poll the prompt for the unlocked state, or to use the Wait(Unlock) action to wait for the unlock.

altCursor

If set, the cursor will be an underline. If clear, it will be a solid block.

blankFill

If set, wc3270 modifies interactive 3270 behavior in two 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.

crosshair

When set, wc3270 will display a crosshair to help locate the cursor on the screen.

lineWrap

If set, the NVT terminal emulator automatically assumes a NEWLINE character when it reaches the end of a line.

marginedPaste

If set, pasting multi-line input via the Paste action will maintain a left margin (it will not move the cursor further left than where the paste begins).

monoCase

If set, wc3270 operates in uppercase-only mode.

overlayPaste

If set, pasting over a protected field will simply increment the cursor position instead of locking the keyboard. This allows forms to be copied and pasted with the protected fields included. Setting this toggle also implicitly sets the marginedPaste toggle.

screenTrace

Turns on screen tracing at start-up. Each time the screen changes, its contents are appended to the file x3scr.pid.txt on the current user's desktop.

showTiming

If set, the time taken by the host to process an AID is displayed on the status line.

trace

Turns on data stream and event tracing at start-up. Network traffic (both a hexadecimal representation and its interpretation) is logged to the file x3trc.pid.txt on the current user's desktop. The directory for the trace file can be changed with the "wc3270.traceDir" resource. Script commands are also traced.

underscore

If set, wc3270 will display underlined fields by substituting underscore `_' characters for blanks or nulls in the field. Otherwise, these fields will be displayed with a highlighted background. Note that setting underscore also disables the highlighted background for blinking fields. underscore is set by default.

visibleControl

If set, control characters (NULLs, SI/SO and field attributes), which are usually displayed as blanks, are visible on the display. NULs become periods, SO becomes `<', SI becomes `>'. Field attributes are mapped onto the characters 0 through 9 and A through V and are displayed in reverse-video yellow. Field attribute mappings are part of the wc3270 Resources documentation for the visibleControl resource.

Status Line

comm status

The first symbol is always a 4. If wc3270 is in TN3270E mode, the second symbol is a B; otherwise it is an A. If wc3270 is in SSCP-LU mode, the third symbol is an S. Otherwise it is blank.

keyboard lock

If the keyboard is locked, an "X" symbol and a message field indicate the reason for the keyboard lock.

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

The letter "I" indicates that the keyboard is in insert mode.

printer session

The letter "P" indicates that a pr3287 session is active.

secure connection

A green letter "S" indicates that the connection is secured via SSL/TLS.

LU name

The LU name associated with the session, if there is one.

cursor position

The cursor row and column are optionally displayed, zero padded and separated by a "/". Location 001/001 is at the upper left, which is different from the row and columns parameters used with various actions, where the upper left corner is row 0, column 0.

Any of the above actions may be entered at the wc3270> prompt; these commands are also available for use in keymaps (see KEYMAPS). Command names are case-insensitive. Parameters can be specified with parentheses and commas, e.g.:

PF(1)

PF 1

wc3270 also supports the following interactive commands:

Help

Displays a list of available commands.

ScreenTrace

Turns screen tracing (saving screen images to a file) on or off. The command screentrace on enables screen tracing; the command screentrace off disables it. After on, a filename may be specified to override the default trace file name of x3scr.pid.txt. The keyaord on can also be followed by the keyword printer and an optional printer name to direct screen traces directly to the printer.

Show

Displays statistics and settings.

Trace

Turns tracing on or off. The command trace on enables data stream and keyboard event tracing; the command trace off disables it. The qualifier data or keyboard can be specified before on or off to enable or disable a particular trace. After on, a filename may be specified to override the default trace file name of x3trc.pid.txt.

Note that certain parameters to wc3270 actions (such as the names of files and keymaps) are subject to substitutions:

The character ~ at the beginning of a string is replaced with the user's home directory.

Environment variables are substituted using the Unix shell convention of $name or ${name}.

Two special pseudo-environment variables are supported. ${TIMESTAMP} is replaced with a microsecond-resolution timestamp; ${UNIQUE} is replaced with a string guaranteed to make a unique filename (the process ID optionally followed by a dash and a string of digits). ${UNIQUE} is used to form trace file names.

Keymaps

Multiple keymaps may be specified be separating their names with commas. Definitions in later keymaps supercede those in earlier keymaps.

In addition, separate keymaps may be defined that apply only in 3270 mode or NVT mode. For example, the resource definition wc3270.keymap.xxx.nvt or the file xxx.nvt.wc3270km will augment the definition of keymap xxx in NVT mode. Similarly, the resource definition wc3270.keymap.xxx.3270 or the file xxx.3270.wc3270km will augment the definition of keymap xxx in 3270 mode.

Temporary keymaps can also be added or removed while wc3270 is running with the Keymap action. See wc3270-script(1) for details.

Each line (rule) in a keymap specifies actions to perform when a particular key or sequence of keys is pressed. Keymap rules have the following syntax:

[modifier...]<Key>key...: action[(param[,...])] ...

Here is a sample keymap definition from a file:

! Lines beginning with ! are ignored and can
! occur anywhere.
! The line below will be displayed
! by the New Session Wizard.
!description: An example.
! Definition of keymap xxx
!  When Alt-c is pressed, clear the screen.
Alt<Key>c: Clear()
!  When PageUp is pressed, send PF7 to the host.
<Key>PRIOR: PF(7)
!  When Ctrl-a is pressed, then F1, send PF13
!  to the host.
Ctrl<Key>a <Key>F1: PF(13)

Here is the same definition as a resource:

! Lines beginning with ! are ignored, but NOT
! within a definition.
! Note that the \ is required at the end of the
! first line, and \n\ is
! required at the end of every other line except
! the last.
! Definition of keymap xxx
wc3270.keymap.xxx: \
 Alt<Key>c: Clear() \n\
 <Key>PRIOR: PF(7) \n\
 Ctrl<Key>A <Key>F1: PF(13)

The optional Shift, Alt or Ctrl modifiers specify that the Shift, Alt and Ctrl keys are pressed along with the specified key, respectively. The LeftCtrl, RightCtrl, LeftAlt, and RightAlt modifiers specifify a particular Ctrl or Alt key. The Enhanced modifier is also available; Enhanced <Key>ENTER is the keypad Enter key. Key is either an ISO 8859-1 symbol name, such as equal for `=' and a for `a', or a symbolic Windows key name, such as UP. More than one key can be specified, indicating that a sequence of keys must be pressed in order for the rule to be matched. The action is an action from the ACTIONS list above. More than one action may be specified; they will be executed in order.

Keymap entries are case-sensitive and modifier-specific. This means that a keymap for the b key will match only a lowercase b. Actions for uppercase B, or for Alt-B, must be specified separately.

Available symbolic key names are: ADD, ALT, APPS, BACK (BackSpace), BackSpace (alias for BACK), CLEAR, CTRL, DECIMAL, DELETE, DIVIDE, DOWN, END, Enter (alias for RETURN), ESCAPE, Esc (alias for ESCAPE), EXECUTE, F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, F13, F14, F15, F16, F17, F18, F19, F20, F21, F22, F23, F24, HELP, HOME, INSERT, LEFT, LMENU, LWIN (Left Windows key), MULTIPLY, NEXT (Page Down), NUMLOCK, NUMPAD0, NUMPAD1, NUMPAD2, NUMPAD3, NUMPAD4, NUMPAD5, NUMPAD6, NUMPAD7, NUMPAD8, NUMPAD9, PageUp (alias for PRIOR), PageDown (alias for Next), PAUSE, PRINT, PRIOR (Page Up), RETURN (Enter), RIGHT, RMENU, RWIN (Right Windows key), SCROLL, SELECT, SEPARATOR, SHIFT, SLEEP, SNAPSHOT, SUBTRACT, TAB and UP. In addition, any Windows VKey code can be specified in hexadecimal with the syntax VKEY-0xnn.

The base keymap is:

Key	Action
Alt<Key>1	PA(1)
Alt<Key>2	PA(2)
Alt<Key>3	PA(3)
Alt Ctrl<Key>]	Key(0x1d)
Ctrl<Key>]	Escape
Alt<Key>^	Key(notsign)
Ctrl<Key>c	Copy
Alt<Key>k	Keymap
Alt<Key>l	Redraw
Alt<Key>m	Compose
Alt<Key>n	Menu
Ctrl<Key>p	Paste
Alt<Key>p	PrintText
Ctrl<Key>x	Cut
<Key>PRIOR	Scroll(Backward)
<Key>NEXT	Scroll(Forward)
Shift<Key>Fn	PF(n+12)

The base 3270-mode keymap adds:

Key	Action
Ctrl<Key>a	Attn
Alt<Key>a	Attn
Alt<Key>c	Clear
Ctrl<Key>d	Dup
Alt<Key>d	Dup

File Transfer

The Transfer action can be entered at the command prompt with no parameters, which will cause it to prompt interactively for the file names and options. It can also be invoked with parameters to define the entire transfer.

Because of the complexity and number of options for file transfer, the parameters to the Transfer action take the unique form of option=value, and can appear in any order. Note that if the value contains spaces (such as a VM/CMS file name), then the entire parameter must be quoted, e.g., "HostFile=xxx foo a". The options are:

Option	Required?	Default	Other Values
Direction	No	receive	send
HostFile	Yes
LocalFile	Yes
Host	No	tso	vm, cics
Mode	No	ascii	binary
Cr	No	remove	add, keep
Remap	No	yes	no
Exist	No	keep	replace, append
Recfm	No		fixed, variable, undefined
Lrecl	No
Blksize	No
Allocation	No		tracks, cylinders, avblock
PrimarySpace	Sometimes
SecondarySpace	No
Avblock	Sometimes
BufferSize	No	4096

The option details are as follows.

Direction

send to send a file to the host, receive to receive a file from the host.

HostFile

The name of the file on the host.

LocalFile

The name of the file on the local workstation.

Host

The type of host (which dictates the form of the IND$FILE command): tso (the default), vm or cics.

Mode

Use ascii (the default) for a text file, which will be translated between EBCDIC and ASCII as necessary. Use binary for non-text files.

Cr

Controls how Newline characters are handled when transferring Mode=ascii files. remove (the default) strips Newline characters in local files before transferring them to the host. add adds Newline characters to each host file record before transferring it to the local workstation. keep preserves Newline characters when transferring a local file to the host.

Remap

Controls text translation for Mode=ascii files. The value yes (the default) causes wc3270 to remap the text to ensure maximum compatibility between the workstation's character set and encoding and the host's EBCDIC code page. The value no causes wc3270 to pass the text to or from the host as-is, leaving all translation to the IND$FILE program on the host.

Exist

Controls what happens when the destination file already exists. keep (the default) preserves the file, causing the Transfer action to fail. replace overwrites the destination file with the source file. append appends the source file to the destination file.

Recfm

Controls the record format of files created on the host. (TSO and VM hosts only.) fixed creates a file with fixed-length records. variable creates a file with variable-length records. undefined creates a file with undefined-length records (TSO hosts only). The Lrecl option controls the record length or maximum record length for Recfm=fixed and Recfm=variable files, respectively.

Lrecl

Specifies the record length (or maximum record length) for files created on the host. (TSO and VM hosts only.)

Blksize

Specifies the block size for files created on the host. (TSO and VM hosts only.)

Allocation

Specifies the units for the PrimarySpace and SecondarySpace options: tracks, cylinders or avblock. (TSO hosts only.)

PrimarySpace

Primary allocation for a file. The units are given by the Allocation option. Required when the Allocation is specified as something other than default. (TSO hosts only.)

SecondarySpace

Secondary allocation for a file. The units are given by the Allocation option. (TSO hosts only.)

Avblock

Average block size, required when Allocation specifies avblock. (TSO hosts only.)

BufferSize

Buffer size for DFT-mode transfers. Can range from 256 to 32768. Larger values give better performance, but some hosts may not be able to support them.

Overrides the workstation code page used for ASCII file transfers. By default, the system ANSI code page is used.

There are also resources that control the default values for each of the file transfer parameters. These resources have the same names as the Transfer keywords, but with ft prepended. E.g., the default for the Mode keyword is the wc3270.ftMode resource.

The PrintText Action

Multiple arguments can include keywords to control the output of PrintText:

gdi

Print directly to the printer using GDI, instead of creating an RTF file and running WordPad to print it. (This is the default).

wordpad

Create an RTF file and run WordPad to print it. (This was the former default).

dialog

In GDI mode, pop up the Windows print dialog. (This is the default.)

nodialog

In GDI mode, skip the usual Windows print dialog.

file filename

Save the output in a file.

html

Save the output as HTML. This option implies file.

rtf

Save the output as RichText. This option implies file. The font defaults to Courier New and the point size defaults to 8. These can be overridden by the printTextFont and printTextSize resources, respectively.

modi

Render modified fields in italics.

caption text

Add the specified text as a caption above the output. Within text, the special sequence %T% will be replaced with a timestamp.

Nested Scripts

The String Action

The simplest method for nested scripts 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, wc3270 will wait for the host to unlock the keyboard before further processing the string.)

\b	Left
\exxxx	EBCDIC character in hex
\f	Clear*
\n	Enter*
\pan	PA(n)*
\pfnn	PF(nn)*
\r	Newline
\t	Tab
\T	BackTab
\uxxxx	Unicode character in hex
\xxxxx	Unicode character in hex

Note that the numeric values for the \e, \u and \x sequences can be abbreviated to 2 digits. Note also that EBCDIC codes greater than 255 and some Unicode character codes represent DBCS characters, which will work only if wc3270 is built with DBCS support and the host allows DBCS input in the current field.

An example keymap entry would be:

Alt<Key>p: String("probs clearrdr\n")

Note: The strings are in ASCII and converted to EBCDIC, so beware of inserting control codes.

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 wc3270 to start a child process which can execute wc3270 actions. wc3270 listens for connections from the child process on a dynamically-generated TCP port. The Script action is fully documented in wc3270-script(1).

Printer Session Support

The action Printer Start starts a printer session, associated with the current LU. (This works only if the host supports TN3270E.)

The action Printer Start lu starts a printer session, associated with a specific lu.

The action Printer Stop stops a printer session.

The resource wc3270.printer.name specifies the Windows printer used to print each job. It defaults to the value of the $PRINTER environment variable, if set. Otherwise the default system printer is used. This resource also controls the printer used by the PrintText action.

The resource wc3270.printer.options specifies extra options, such as -trace to pass to wpr3287.

See wpr3287(1) for further details.

The resource wc3270.printerLu controls automatic printer session start-up. If it is set to `.', then whenever a login session is started, a printer session will automatically be started, associated with the login session. If it is set an LU name, then the automatic printer session will be associated with the specified LU.

Proxy

type:host[:port]

The special types socks4a and socks5d can also be used to force the proxy server to do the hostname resolution for the SOCKS protocol.

Note 1: m3279 defaults to True. It can be forced to False with the proper -model option.

Note 2: The default terminal type string is constructed from the model number, color emulation, and extended data stream modes. E.g., a model 2 with color emulation and the extended data stream option would be sent as IBM-3279-2-E. Note also that when TN3270E mode is used, the terminal type is always sent as 3278, but this does not affect color capabilities.

Note 3: The default trace file is x3trc.pid.txt on the current user's desktop.

Note 4: See PRINTER SUPPORT for details.

Note 6: The default console color mappings for host colors 0 through 15 are: 0, 9, 12, 13, 10, 11, 14, 15, 0, 1, 12, 5, 2, 3, 7, and 15.

If more than one -xrm option is given for the same resource, the last one on the command line is used.
