NAME
atty - Asian terminal driver
SYNOPSIS
#include <sys/aioctl.h>
DESCRIPTION
This reference page describes the additional features supported in the
Asian terminal driver used for conversational computing in a Japanese,
Chinese, or Korean environment. See tty(7) for a description of the
general terminal interface. See stty(1) for information on how to activate
the features discussed here.
The Asian terminal driver is available only if you install the Tru64 UNIX
optional subsets for worldwide support. The Asian terminal driver must be
configured into the current running kernel in order for the features
described below to be enabled.
Line Disciplines
Line discipline switching to the Asian terminal driver is accomplished with
the TIOCSETD ioctl as follows:
int ldisc = ASYDISC;
ioctl(f, TIOCSETD, &ldisc);
Input Editing
A character for the Asian terminal driver can be composed of one or more
bytes, depending on the terminal codeset selected by the user. In addition,
the ISTRIP mask of the c_iflag field does not work with this driver. The
erase character (VERASE) logically erases the whole character, which may be
more than one byte long.
Code Conversion
The Asian terminal driver allows an application to communicate with the
driver in one codeset while the driver communicates with the physical
device in another codeset. These two different codesets are called the
application codeset and the terminal codeset, respectively. The driver
performs any necessary codeset conversion on data passed between your
application and the device.
The following application codesets are supported by the Asian terminal
driver. The keyword that specifies the codeset in command parameters is
shown in parentheses.
· DEC Kanji (deckanji)
· Super DEC Kanji (sdeckanji)
· Japanese EUC (eucJP)
· Shift JIS (SJIS)
· DEC Hanzi (dechanzi)
· DEC Hanyu (dechanyu)
· Taiwanese EUC (eucTW)
· DEC Korean (deckorean)
· Korean EUC (eucKR)
· UTF-8 (UTF-8)
· Big-5 (big5)
Reference pages are available for each codeset; for example, to find out
more about the DEC Korean codeset, see deckorean(5).
The following terminal codesets are supported by the Asian terminal driver.
The keyword that specifies the codeset in command parameters is shown in
parentheses.
· DEC Kanji (dec)
· DEC Kanji - 1978 (dec78)
· Japanese EUC (eucJP)
· Shift JIS (SJIS)
· 7-bit JIS (jis7)
· 8-bit JIS (jis8)
· DEC Hanzi (dechanzi)
· Taiwanese EUC (eucTW)
· DEC Korean (deckorean)
· Korean EUC (eucKR)
· UTF-8 (UTF-8)
· Big-5 (big5)
· Telecode (telecode)
By default, the Asian terminal driver supports all listed codesets except
for Big-5, Telecode, and UTF-8. Support for the BIG-5, UTF-8, and Telecode
codesets requires linking additional modules (that are supplied in optional
subsets) into the kernel.
History Mode Line Editing
The history mode supported by the Asian terminal driver allows the user to
have Emacs-like control for editing previously entered command lines. Up to
32 lines can be stored in history mode, and each line can have a maximum
length of 127 characters. When commands are long, it is possible that
fewer than 32 commands are stored in the history list. Short commands,
those less than three characters (single-byte or multibyte) in length, are
not stored in the history list.
The following editing commands are available in history mode:
Ctrl/A
Move to the beginning of line.
Ctrl/D
Delete the character under the cursor.
Ctrl/E
Move to the end of the line.
Up-Arrow
Recall the previous command in the history list.
Down-Arrow
Recall the next command in the history list.
Left-Arrow
Move the cursor left by one character.
Right-Arrow
Move the cursor right by one character.
erase-char
Delete the character before the cursor. You can use the stty command to
determine and set the character that erases a character.
werase-char
Delete the word before the cursor. You can use the stty command to
determine and set the character that erases a word.
Typing a normal character causes it to be inserted before the character
under the cursor. The kill, interrupt, and suspend characters cause the
Asian terminal driver to break out of history mode.
Kana-Kanji Conversion
The Kana-Kanji conversion mechanism for Japanese allows users to enter an
ASCII or Kana string and convert it to a Kanji or another Kana string. The
conversion is supported in both cbreak and cooked mode, but activation of
Kana-Kanji conversion is different for each mode. See kkc(5) for more
information about Kana-Kanji conversion. See stty(1) on how to activate
Kana-Kanji conversion under different modes.
Software On-Demand Loading
The Software On-Demand Loading (SoftODL) mechanism allows users to display
any number of user-defined characters (UDC) on terminals that support
hardware On-Demand Loading (ODL). Refer to odl(5) for more information
about on-demand loading of UDCs.
Software Phrase Input Method
The Software phrase Input Method (SIM) mechanism for Chinese allows users
to enter a long phrase by typing in a short phrase key. Refer to sim(5) for
more information on this input mechanism.
