NAME

kterm - terminal emulator for X

SYNOPSIS

kterm [-toolkitoption ...] [-option ...]

DESCRIPTION

The kterm program is a Kanji terminal emulator for the X Window System. It provides DEC VT102 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. It comes from xterm in the core programs of the distribution of the X Window System. The most of the functions are the same as original xterm's, however, it has capabilities of displaying Kanji strings and handling of the status line, if compiled with -DKANJI or -DSTATUSLINE compile time options.

OPTIONS

The kterm terminal emulator accepts all of the standard xterm command line options along with the additional options listed below (if the option begins with a `+' instead of a `-', the option is restored to its default value):

-fk kanji-font: This option specifies a Kanji font to be used when displaying Kanji text. This font must be the same height and width as the ascii font. The default is ``a14''.
-fkb kanji-bold-font: This option specifies a Kanji bold font to be used when displaying bold text. This font must be the same height and width as the kanji font. If no Kanji bold font is specified, it will be used as the normal font and the bold font will be produced by overstriking this font. The default is not specified.
-fr kana-font: This option specifies a Kana font, which may be used as GR in 8bit environment. This font is used if ``ESC ( I'' is appeared in JIS Kanji mode, SS2 (0x8e) is appeared in EUC Kanji mode, and not used so frequntly in normal Japanese text. The default is ``kana14''.
-frb kana-bold-font: This option specifies a Kana bold font.
-ka: This option indicates that kterm should connect to the X server with KEEPALIVE socket option. It is usefull when the server is a X terminal that is frequently powered off. This option is accepted only if kterm has been compiled with -DKEEPALIVE compile option.
+ka: This option indicates that kterm should connect to the X server without KEEPALIVE socket option.
-km kanji-mode: This option specifies the Kanji code from the pty output. If kanji-mode is ``jis'', then it assumes the input/output is coded by JIS code, i.e., each Kanji string is proceeded by ``ESC $ B'' or ``ESC $ @'' and each ascii string is proceeded by ``ESC ( B'' or ``ESC ( J''. This mode does not require 8 bit passing tty module because 7 bit encoding with appropriate escape sequences is used. If kanji-mode is ``euc'', then it assumes the input/output is coded by EUC. If kanji-mode is ``sjis'', then it assumes the input/output is coded by Shift-JIS code (which is the same as MicroSoft Kanji code). The default mode is ``jis''.
-sn: By default, the status line is in reverse-video (relative to the rest of the window). This option causes the status line to be in normal video (the status line is still enclosed in a box).
-st: This option causes the status line to be displayed on startup.

X DEFAULTS

The program understands all of the core xterm resource names and classes as well as:

kanjiFont (class KanjiFont): Specifies the name of the kanji font. The default is ``a14.''
kanjiboldFont (class KanjiFont): Specifies the name of the bold font. The default is not specified.
kanaFont (class KanaFont): Specifies the name of the kana font. The default is ``kana14.''
kanaboldFont (class KanaFont): Specifies the name of the bold font. The default is not specified.
kanjiMode (class KanjiMode): Specifies the Kanji code of pty output. The default is ``jis.''
keepAlive (class KeepAlive): Specifies whether or not kterm should connection to the X server with KEEPALIVE socket option. The default is ``false.''
statusLine (class StatusLine): Causes the status line to be displayed on startup. The default is ``false.''
statusNormal (class StatusNormal): Specifies whether or not the status line should be in normal video. The default is ``false.''

EMULATIONS

The VT102 emulation is fairly complete, but does not support the blinking character attribute nor the double-wide and double-size character sets. Termcap(5) entries that work with xterm include ``kterm'', ``xterm'', ``vt102'', ``vt100'' and ``ansi'', and xterm automatically searches the termcap file in this order for these entries and then sets the ``TERM'' and the ``TERMCAP'' environment variables.

BUGS

Kterm assumes that the width of Kanji characters is as twice as that of ASCII characters. Of course variable-width fonts are not handled like xterm.

This version of kterm uses ``ESC $ B'' to designate the Kanji character set in tty output when JIS mode is selected. There is no way to specify ``ESC $ ( B'' instead.

Because of a historical reason in Japan, the sequence to designate Swedish character set ``ESC ( H'' is treated as that of Japanese roman character set.

There is no distinction between ASCII and Japnese roman character sets, though the latter includes the ``Yen'' character, interrupted bar and upper score.

Currently available xterm nor previously released kterm can not paste a Kanji text from this kterm. Because we are not allowed to store the cutted Kanji text into the cut buffer or selection with STRING type, as defined in the ICCCM,
