TN5250(1)

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:

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

•   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.

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 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.
