       c3270 - curses-based IBM host access tool

       c3270 [options] [host]

       c3270  opens  a	telnet connection to an IBM host in a console window.  It implements RFCs
       2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selection),  and  supports  IND$FILE  file
       transfer.   If  the  console  is  capable of displaying colors, then c3270 emulates an IBM
       3279.  Otherwise, it emulates a 3278.

       The full syntax for host is:

       Prepending a p: onto hostname causes the connection to go through the telnet-passthru ser-
       vice 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 commas.  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 c3270 to connect to a local child process, such as a

       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 c3270 and with tn3270(1), the port may also be specified as a second, separate

	c3270 understands the following options:

	      Forces  all  characters to be displayed in bold.	This helps with PC consoles which
	      display non-bold characters in unreadably dim colors.

       -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  TOG-
	      GLES below.

       -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.

       -keymap name
	      Specifies a keyboard map to be found in the resource c3270.keymap.name or the  file
	      name.  See KEYMAPS below for details.

       -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.

	      The  second  part  is the model number, which specifies the number of rows and col-
	      umns.  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 display is 3279-4.  For a monochrome display, it is

       -mono  Forces 3278 emulation.

       -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
	      "c3270.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 c3270 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.

       -set toggle
	      Sets  the  initial  value  of  toggle  to  true.	The list of toggle names is under
	      TOGGLES 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 display, or
	      IBM-3278-4-E for a monochrome 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 "c3270.extended" resource to "false", removes the -E from the  terminal
	      name when connecting to such hosts.

	      The name can also be specified with the "c3270.termName" resource.

       -trace Turns  on data stream and event tracing at startup.  The default trace file name is

       -tracefile file
	      Specifies a file to save data stream and event traces into, overriding the  default
	      of /tmp/x3trc.process_id.

       -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

       -xrm "c3270.resource: value"
	      Sets the value of the named resource to value.  Resources control less common c3270
	      options, and are defined under RESOURCES below.

       The -charset option or the "c3270.charset" resource controls the EBCDIC host character set
       used by c3270.  Available sets include:

			  Charset Name	 Code Page   Display Character Sets
			  apl		 37	     3270cg-1a
			  belgian	 500	     3270cg-1a 3270-cg1
			  bracket	 37	     3270cg-1a 3270-cg1

			  uk		 285	     3270cg-1a 3270-cg1
			  us-intl	 37	     3270cg-1a 3270-cg1

       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.

       c3270  uses the ibm_hosts database to define aliases for host names, and to specify 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 "c3270.hostsFile" resource.

       Some hosts use an ASCII front-end to do initial login negotiation, then	later  switch  to
       3270 mode.  c3270 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).

       If the host later negotiates to stop functioning in 3270 mode, c3270 will return  to  ANSI

       In  NVT	mode,  c3270 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	      c3270.icrnl     true
			   Translate NL to CR	      c3270.inlcr     false
			   Erase previous character   c3270.erase      ^?
			   Erase entire line	       c3270.kill      ^U
			   Erase previous word	      c3270.werase     ^W
			   Redisplay line	      c3270.rprnt      ^R
			   Ignore special meaning     c3270.lnext      ^V
			   of next character
			   Interrupt		       c3270.intr      ^C
			   Quit 		       c3270.quit      ^\
			   End of file		       c3270.eof       ^D

       Separate keymaps can be defined for use only when c3270 is in 3270 mode or NVT mode.   See
       KEYMAPS for details.

       c3270  has  a  number  of  configurable modes which may be selected by the -set and -clear

	      If set, c3270 operates in uppercase-only mode.

	      If set, c3270 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.

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

       The names of the toggles for use with the -set and -clear options are as follows:

				  Option		   Name
				  Monocase		   monoCase
				  Blank Fill		   blankFill
				  Track Cursor		   cursorPos
				  Trace Data Stream	   dsTrace
				  Trace Events		   eventTrace
				  Save Screen(s) in File   screenTrace
				  Wraparound		   lineWrap

       These names are also used as the first parameter to the Toggle action.

       If the terminal that c3270 is running on has at least one more row  that  the  3270  model
       requires  (e.g.,  25  rows  for	a  model 2), c3270 will display a status line.	The c3270
       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.

	      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.

	      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.

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

       cursor position
	      The cursor row and column are optionally displayed, separated by a "/".

       Here is a complete list of basic c3270 actions.	Script-specific actions are described  on
       the x3270-script(1) manual page.

       Any  of	the  above  actions  may be entered at the c3270> 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.:
       or with spaces, e.g.:
	      PF 1
       Parameters  can	be  quoted  with  double-quote	characters,  to allow spaces, commas, and
       parentheses to be used.

       c3270 also supports the following interactive commands:

       Help   Displays a list of available commands.

       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

       The -keymap option allows a keymap to be specified.  If the option -keymap xxx  is  given,
       then  c3270  will  first look for a resource named c3270.keymap.xxx; if that is not found,
       then it will look for a file named xxx.

       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 only in NVT
       mode.   For  example,  the  resource  definition  c3270.keymap.xxx.nvt  will  augment  the
       definition  of  c3270.keymap.xxx,  when	c3270  is  in  NVT mode.  Similarly, the resource
       definition c3270.keymap.xxx.3270 will augment the  definition  of  c3270.keymap.xxx,  when
       c3270 is in 3270 mode.

       Keymaps	specify  actions  to perform when a particular sequence of keys is pressed.  Each
       line in a keymap has the following syntax:

	      [Meta][Ctrl]<Key>key...: Action[(param[,...])] ...

       For example:

	      Meta<Key>c: Clear()
	      <Key>PPAGE: PF(7)
	      Ctrl<Key>A <Key>F1: PF(13)

       The optional Meta or Ctrl qualifiers specify that the Meta and Ctrl keys are pressed along
       with the specified key, respectively.  The key is either a valid X11 keysym (these are the
       ISO 8859-1 symbol names, such as equal for `=' and a for `a') or a valid symbolic  ncurses
       key  name,  such  as UP.  The Action is an action from the ACTIONS list, above.	More than
       one action may be specified.  (Note that symbolic ncurses key names can be  used  only  if
       the c3270.cursesKeymap resource is set to True, which enables ncurses keymap mode.)

       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 Meta-b or Control-B,
       must be specified separately.

       The base keymap is:

       Key		       Action
       Ctrl<Key>]	       Escape
       Ctrl<Key>a Ctrl<Key>a   Key(0x01)
       Ctrl<Key>a Ctrl<Key>]   Key(0x1d)
       Ctrl<Key>a <Key>Tab     BackTab
       Ctrl<Key>a <Key>c       Clear
       Ctrl<Key>a <Key>e       Escape
       Ctrl<Key>a <Key>r       Reset
       Ctrl<Key>a <Key>l       Redraw
       Ctrl<Key>a <Key>m       Compose
       Ctrl<Key>a <Key>^       Key(notsign)
       <Key>UP		       Up
       <Key>DOWN	       Down
       <Key>LEFT	       Left
       <Key>RIGHT	       Right
       <Key>F(n)	       PF(n)
       Ctrl<Key>a <Key>F(n)    PF(n+12)
       Ctrl<Key>a <Key>1       PA(1)
       Ctrl<Key>a <Key>2       PA(2)
       Ctrl<Key>a <Key>3       PA(3)

       The base 3270-mode keymap adds:

       Key		Action
       Ctrl<Key>c	Clear
       Ctrl<Key>r	Reset
       Ctrl<Key>l	Redraw
       <Key>Tab 	Tab
       <Key>DC		Delete
       <Key>BACKSPACE	BackSpace
       <Key>BackSpace	BackSpace
       <Key>Return	Enter
       <Key>Linefeed	Newline

       Some keyboards do not have a Meta key.  Instead, they have an Alt key.  Sometimes this key
       acts as a proper Meta key, that is, it is a modifier key  that  sets  the  high-order  bit(0x80) in the code that is transmitted for each key.  Other keyboards send a two-character
       sequence when the Alt key is pressed  with  another  key:  the  Escape  character(0x1b),
       followed by the code for the other key.

       The  resource  c3270.metaEscape	and  the  termcap  km  attribute  control  how c3270 will
       interpret these sequences.  When c3270.metaEscape is set to true, or when c3270.metaEscape
       is  set	to  auto  and  the termcap km attribute is set, the keyboard is assumed to have a
       separate Meta key.  The Escape key can be used as an ordinary data key and has no  special

       When  c3270.metaEscape  is  set	to  true, or when c3270.metaEscape is set to auto and the
       termcap km attribute is not set, the keyboard is assumed to use the Escape character as	a
       prefix  to  indicate  that  the following character is supposed to have the high-order bit
       set.  When c3270 sees an Escape character from the keyboard, it sets a short timeout.   If
       another	character  arrives  before  the  timeout expires, then c3270 will combine the two
       characters, setting the high-order bit of  the  second.	 In  an  event	trace  file,  the
       combined  character is listed as derived.  In a keymap, only the combined character or the
       Meta prefix may be used.  The Escape key can still be used by itself, but only if there is
       a short pause before pressing another key.

       The default value for c3270.metaEscape is auto.

       The  Transfer  action  implements  IND$FILE  file transfer.  This action requires that the
       IND$FILE program be installed on the IBM host, and that the 3270 cursor be  located  in	a
       field that will accept a TSO or VM/CMS command.

       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.   The
       options are:

       Option		Required?   Default   Other Values
       Direction	   No	    send      receive
       HostFile 	   Yes
       LocalFile	   Yes
       Host		   No	    tso       vm
       Mode		   No	    ascii     binary
       Cr		   No	    remove    add, keep
       Exist		   No	    keep      replace, append
       Recfm		   No		      fixed, variable,
       Lrecl		   No
       Blksize		   No
       Allocation	   No		      tracks, cylinders,
       PrimarySpace	   No
       SecondarySpace	   No

       The option details are as follows.

	      send  (the  default) to send a file to the host, receive to receive a file from the

	      The name of the file on the host.

	      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) or vm.

       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.

       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.	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

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

	      Specifies the units for the  TSO	host  PrimarySpace  and  SecondarySpace  options:
	      tracks, cylinders or avblock.

	      Primary  allocation  for	a file created on a TSO host.  The units are given by the
	      Allocation option.

	      Secondary allocation for a file created on a TSO host.  The units are given by  the
	      Allocation option.

       There are several types of script functions available.

       The String Action
	      The simplest method for scripting 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, c3270 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.

	      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 c3270 to start a child process which can execute c3270 actions.
	      Standard input and output from the child process are  piped  back  to  c3270.   The
	      Script action is fully documented in x3270-script(1).

       c3270  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 "c3270.composeMap" resource; it gives the name of the map to  use.   The
       maps  themselves  are named "c3270.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 Meta<Key>m as the "Compose" key.  You may set up your own
       "Compose" key with a keymap that maps some other keysym onto the Compose action.

       c3270 supports associated printer sessions via the pr3287(1) program.  The Printer  action
       is used to start or stop a pr3287 session.

       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 c3270.printer.command specifies the  command  used	to  print  each  job;  it
       defaults  to  lpr.  The resource c3270.printer.assocCommandLine specifies the command used
       to start an associated printer session.	It defaults to:

	      pr3287 -assoc %L% -command "%C%" %H%

       The resource c3270.printer.luCommandLine specifies the command used to start a specific-LU
       printer session.  It defaults to:

	      pr3287 -command "%C%" %L%@%H%

       When the printer session command is run, the following substitutions are made:

       Token   Substitition
       %C%     Command (value of
       %H%     Host IP address
       %L%     Current or specified LU

       See pr3287(1) for further details.

       c3270 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, c3270 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.

       Certain c3270 options can be configured via resources.  Resources are defined in the  file
       .c3270pro  in the user's home directory, and by -xrm options.  The definitions are similar
       to X11 resources, and use a similar syntax.  The resources available in c3270 are:

       Resource       Default	 Option 	  Purpose
       allBold	      Auto	 -allbold	  Display all
						  characters bold
       blankFill      False	 -set blankFill   Blank Fill mode
       charset	      bracket	 -charset	  EBCDIC character
       charset.foo				  Definition of
						  character set foo

       composeMap     latin1			  Name of composed-
						  character map
       cursesKeymap   True			  Set curses keymap
       dsTrace	      False	 -trace 	  Data stream tracing

       numericLock    False			  Lock keyboard for
						  numeric field error
       oerrLock       True			  Lock keyboard for
						  input error
       oversize 		 -oversize	  Oversize screen
       port	      telnet	 -port		  Non-default TCP
       printer.*      (note 4)			  Printer session
       quit	      ^\			  NVT-mode quit
       rprnt	      ^R			  NVT-mode reprint
       secure	      False			  Disable "dangerous"
       termName       (note 2)	 -tn		  TELNET terminal
						  type string
       traceDir       /tmp			  Directory for trace
       traceFile      (note 3)	 -tracefile	  File for trace
       typeahead      True			  Allow typeahead
       werase	      ^W			  NVT-mode word-erase

	      Note 1: m3279 defaults to True if the terminal supports color, False otherwise.  It
	      can be forced to False with the -mono 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 some  type
	      of 3278.

	      Note  3:	The  default  trace  file  is x3trc.pid in the directory specified by the
	      traceDir resource.

	      Note 4: See PRINTER SUPPORT for details.

       In .c3270pro, lines are continued with a backslash character.

       -xrm options override definitions found in .c3270pro.  If more than  one  -xrm  option  is
       given for the same resource, the last one on the command line is used.
