TN5250(1)                                                            TN5250(1)


       tn5250 - an implementation of the 5250 telnet protocol


       tn5250 [OPTIONS] host[:port]
       xt5250 [OPTIONS] [host[:port]]
       tn5250 -version


       tn5250  emulates IBM’s 5250 compatible terminals to connect over TCP/IP
       to an IBM AS/400.  The terminal emulation works on any  local  terminal
       supported  by curses, and provides 132x27 and full colour support where

       tn5250 will connect to the given host’s telnet  port,  or  a  different
       port  if specified.  The host name may be preceded by a protocol: which
       specifies either to use telnet to the host, if omitted or set to telnet
       or  tn5250, or to replay a session dumped using the trace option if set
       to debug.

       An IBM 5250 terminal supports a number of special keys, and does a  lot
       of processing itself before sending data to the host system.  Because a
       standard ASCII terminal does not support all these  keys,  tn5250  uses
       control sequences to perform the operations.

       Named  session  support  (with the env.DEVNAME option) is available for
       most versions of OS/400, but is only supplied with V4R3 and later  ver-
       sions.   For  V3R2,  V3R7, V4R1 and V4R2, please see informational APAR


              Log all tn5250 actions to tracefile.  This file  will  get  very
              large,  and  may contain sensitive information such as the pass-
              word used to log in.

              Set the translation table between ASCII and EBCDIC.  This should
              match  the CCSID of the interactive job.  The default for tn5250
              is 37.  See Translation Maps below for more information.

              Set the device name for the AS/400 to assign to  the  5250  ses-
              sion.   This  should be up to ten characters long and consist of
              only letters and numbers.  It will be converted to uppercase and
              used  as  the  name of the 5250-compatible device on the AS/400.
              There may only be one session active with any given name at  one

              Set  the  terminal  model name for the emulation session to use.
              The default depends on whether the terminal supports colour, and
              whether  it  is large enough to support the large terminal size.
              See Display Types below for valid model names.

              Set any other environment  variables  controlling  the  terminal
              session.   A list of relevant variables is given in section 5 of

              Force or disable the use of underscore characters instead of the
              underline   attribute,   for   terminals  that  do  not  support
              underlining but where tn5250 does not work this out itself.

              Turn the ruler feature on or off.  When  enabled,  the  row  and
              column of the cursor will be highlighted.

              Display the version of tn5250 and exit.


       These are some examples of the use of tn5250:

       tn5250 as400sys
              Connect  to  the  system as400sys, using the default translation
              map (37) and a generated session name (QPADEV####).

       tn5250 map=870 env.DEVNAME=session1 env.TERM=IBM-3477-FC as400sys
              Connect to as400sys using the  translation  map  for  CCSID  870
              (Eastern  Europe), the session name SESSION1 and with a terminal
              supporting colour and a 132x27 display.


       This manual assumes that the user is familiar with a real  5250  termi-
       nal,  or another 5250 emulator, and only describes features relevant to
       tn5250 itself.

   Keyboard Mapping
       The following table lists the 5250 functions implemented by tn5250, and
       the  corresponding keypresses.  Keys are represented as Emacs does: C-a
       means hold Ctrl and press A, M-a means press Esc or C-g followed by  A,
       and C-M-a means press Esc or C-g followed by C-a.  Most setups also let
       you use the Alt or Meta key for M- keypresses.

       Function     Keypress
       F1 - F10     f1 to f10, M-1 to M-
       F11          f11 [1], M--
       F12          f12 [1], M-=
       F13 - F24    f13 to f24 [1], M-! to M-+
       Enter        return, enter, C-j, C-m
       Left         left
       Right        right
       Up           up
       Down         down
       Roll Up      next, pagedown, C-d, C-f
       Roll Down    prev, pageup, C-b, C-u
       Backspace    backspace [1]
       Home         home, C-o
       End          end
       Insert       insert, M-i, M-delete
       Delete       delete [1]
       Reset        C-r, M-r
       Print        C-p, M-p
       Help         M-h
       SysReq       C-c, M-s
       Clear        M-c
       FieldExit    C-k, M-x
       TestReq      C-t
       Toggle       M-t
       Erase        C-e
       Attn         C-a, M-a
       Dup          M-d
       Field+       C-x, + [2]
       Field-       M-m, - [2]
       NewLine      C-M-j

       Next Field   tab, C-i
       Prev Field   backtab [1]
       Refresh      C-l, M-l
       Quit         C-q

       [1]    Which keys generate f11-f24, backtab, backspace  and  delete  is
              very dependent on the configuration of the terminal.

       [2]    + and - only work as Field+ and Field- in signed numeric fields.

       The screen display tries to be the same  as  a  colour  5250  terminal.
       There are some unavoidable differences though:

              ASCII terminals (and curses) do not support the 5250 column sep-

              Some terminals (mostly ones based on the VGA text mode)  do  not
              support  underlining.   If  this is the case and tn5250 does not
              detect it automatically, you should pass the -u option.

              Some terminals (such as xterm) do not support blinking text.

   Display Types
       The following values are valid  for  the  terminal  name  option.   The
       default  terminal,  if  none  is  specified, is selected from the first
       listed below that supports both terminal size and colour support.

   Translation Maps
       CCSIDs  on  the  AS/400  are  listed  in  Appendix  G  of  IBM   manual
       SC41-5101-01,  AS/400 National Language Support.  This manual is avail-
       able  on  the   web   at   <

       Currently  recognised values for the translation map are: 37, 256, 273,
       277, 278, 280, 284, 285, 290, 297, 420, 424, 500, 870, 871,  875,  880,
       905,  and 1026.  Most of these are translated to ISO-8859-1, also known
       as Latin 1.  Some of them contain characters only  present  in  another
       encoding,  which is used instead.  The valid CCSID values, and the Unix
       encoding used, are listed below.

       If possible, configure your terminal to use the appropriate encoding if
       your AS/400 uses any of these CCSIDs.
