c3270 - curses-based IBM host access tool


SYNOPSIS

       c3270 [options] [host]


DESCRIPTION

       c3270  opens  a telnet connection to an IBM host in a con­
       sole window.  It  implements  RFCs  2355  (TN3270E),  1576
       (TN3270)  and  1646  (LU  name  selection),  and  supports
       IND$FILE file transfer.

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


OPTIONS

       c3270 understands the following options:

       -charset name
              Specifies  an  EBCDIC  national 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.

              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 three parts, any 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 speci­
              fies 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  third  part  specifies  the Extended 3270 Data
              Stream, and is given as -E.  It  signals  the  host
              that  the  3270  display  is  capable of displaying
              extended field attributes, and supports  structured
              fields  and  query replies.  A 3279 always uses the
              Extended Data Stream (whether or not -E  is  speci­
              fied); for a 3278 it is optional.

              The  default model for a color display is 3279-4-E.
              For a monochrome display, it is 3278-4-E.

       -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
              (the  -E suffix on the model), and only if the host
              supports the Query  Reply  structured  field.   The
              number  of columns multiplied by the number of rows

              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 num­
              ber used  for  all  connections.   (The  positional
              parameter affects only the initial connection.)

       -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, 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 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  /tmp/x3trc.pro­
              cess_id.

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

       -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.


CHARACTER SETS

       The  -charset  option or the "c3270.charset" resource con­
       trols the EBCDIC national character  set  used  by  c3270.
       Available sets include:

                        Charset Name   Q121 Code
                        -------------------------
                        bracket            -
                        us-intl           01

                        finnish           09
                        uk                22
                        norwegian         23
                        french            30
                        icelandic          -
                        belgian            -
                        italian            -

       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.


HOSTS DATABASE

       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.


NVT (ANSI) MODE

       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 emulation.

       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 of next character   c3270.lnext      ^V
    Interrupt                                   c3270.intr      ^C
    Quit                                        c3270.quit      ^\
    End of file                                 c3270.eof       ^D

       A separate keymap can be defined for use only  when  c3270
       is in NVT mode.  See KEYMAPS for details.


TOGGLES

       c3270  has  a  number  of  configurable modes which may be


       monoCase
              If set, c3270 operates in uppercase-only mode.

       blankFill
              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.

       lineWrap
              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


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 mes­
              sage  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


       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.

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

       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-insensi­
       tive.  Parameters can be specified  with  parentheses  and
       commas, e.g.:
              PF(1)
       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 /tmp/x3trc.pid.


KEYMAPS

       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

       those in earlier keymaps.

       In  addition,  separate  keymaps may be defined that apply
       only in NVT mode.  For example,  the  resource  definition
       c3270.keymap.xxx.nvt   will  override  the  definition  of
       c3270.keymap.xxx, when c3270 is in NVT  mode.   Similarly,
       the keymap in the file xxx.nvt will override the keymap in
       the file xxx, when c3270 is in NVT 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 ncurses key name, such as UP.  The
       Action is an action from the ACTIONS  list,  above.   More
       than one action may be specified.

       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
       ------------------------------------
       <Key>Escape            Escape
       Meta<Key>c             Clear
       Ctrl<Key>a <Key>c      Clear
       Meta<Key>r             Reset
       Ctrl<Key>a <Key>r      Reset
       Meta<Key>l             Redraw
       Ctrl<Key>a <Key>l      Redraw
       Meta<Key>m             Compose
       Ctrl<Key>a <Key>m      Compose
       <Key>Tab               Tab
       Ctrl<Key>a <Key>Tab    BackTab
       Meta<Key>^             Key(notsign)
       <Key>DC                Delete
       <Key>BACKSPACE         BackSpace

       <Key>Return            Enter
       <Key>Linefeed          Newline
       <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)
       Meta<Key>1             PA(1)
       Ctrl<Key>a <Key>1      PA(1)
       Meta<Key>2             PA(2)
       Ctrl<Key>a <Key>2      PA(2)
       Meta<Key>3             PA(3)
       Ctrl<Key>a <Key>3      PA(3)

       For keyboards which do not have a Meta key,  there  is  an
       additional  keymap  defined, called nometa.  (On some sys­
       tems, this is added by default.)  The nometa  keymap  uses
       the  Escape key as a substitute for the Meta key.  So, for
       example, the 3270 PA1 action would be invoked by  pressing
       the Escape key, then the 1 key.


FILE TRANSFER

       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  com­
       mand.

       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, undefined
       Lrecl               No
       Blksize             No
       Allocation          No                 tracks, cylinders, avblock
       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 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) or vm.

       Mode   Use ascii (the default) for a text file, which will
              be  translated  between  EBCDIC and ASCII as neces­
              sary.  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 desti­
              nation 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 host.

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

       Allocation
              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.

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


SCRIPTS

       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 key n*
              \pfnn   PF key nn*
              \r      Newline
              \t      Tab

              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 spe­
       cial 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 pend­
       ing composite character.

       The  mappings between these pairs of ordinary keys and the
       symbols they represent is controlled  by  the  "c3270.com­
       poseMap"  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 "Com­
       pose" key.  You may set up your own "Compose" key  with  a
       keymap  that  maps  some  other  keysym  onto  the Compose
       action.


PRINTER SUPPORT

       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, associ­
       ated  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

       %H%     Host IP address
       %L%     Current or specified LU

       See pr3287(1) for further details.


PASSTHRU

       c3270 supports the Sun telnet-passthru service provided by
       the in.telnet-gw server.  This allows outbound telnet con­
       nections  through  a  firewall  machine.   When  a  p:  is
       prepended to a hostname, c3270 acts much  like  the  itel­
       net(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.


RESOURCES

       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
       --------------------------------------------------------------------------------

       werase        ^W                          NVT-mode word-erase character

              Note 1: m3279 defaults to True if the terminal sup­
              ports  color, False otherwise.  It can be forced to
              False with the -mono option.

              Note 2: The default terminal type  string  is  con­
              structed  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 charac­
       ter.

       -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.
