NAME
       tn5250 - an implementation of the 5250 telnet protocol

SYNOPSIS
       tn5250 [OPTIONS] HOSTNAME
       xt5250 [OPTIONS] HOSTNAME
       tn5250 -version

DESCRIPTION
       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 possible.

       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 versions.  For V3R2, V3R7, V4R1 and V4R2,
       please see informational APAR II10918.

OPTIONS
       tn5250 options are described in the tn5250rc(5) man page.

USAGE
       This  manual  assumes that the user is familiar with a real 5250 terminal, 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.

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

       o  ASCII terminals (and curses) do not support the 5250 column separators.

       o  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.

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

EXAMPLES
       These are some examples of the use of tn5250:

       tn5250 as400sys
	      Connect to the system as400sys, using the default translation map (37) and a gener-
	      ated 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.

BUGS
       Please  report any bugs you find to the bug tracker or to the linux5250 mailing list.  See
       the tn5250 web site for more details.
