jconv8(7M) STREAMS Modules jconv8(7M)
NAME
jconv8 - code conversion STREAMS module (8-bit JIS/Japanese EUC)
SYNOPSIS
#include <sys/types.h>
#include <sys/stropt.h>
#include <sys/conf.h>
ioctl(fd, I_PUSH, "jconv8");
DESCRIPTION
jconv8 is a STREAMS module that is available to be pushed onto a stream. Usually, this module has to be pushed onto a stream between a raw
device such as ptem(7M) and terminal line discipline module such as ldterm(7M).
jconv8 has to be pushed when you set 8-bit JIS terminal and control Japanese EUC data. It converts up stream for 8-bit JIS code into Japa-
nese EUC and passes high module. It also converts down stream for Japanese EUC into 8-bit JIS code and passes low module.
IOCTLS
jconv8 processes the following ioctls. JA_SKIOC and JA_GKIOC are specified pointer to the next structure as argument:
struct kioc {
char ki;
char ko;
};
JA_SKIOC Change the 3rd character of JIS kanji and ASCII indication escape sequence.
JA_GKIOC Return the 3rd character of current JIS kanji and ASCII indication escape sequence.
EUC_OXLON Start performing code conversion between 8-bit JIS and Japanese EUC for I/O stream.
EUC_OXLOFF Stop performing code conversion between 8-bit JIS and Japanese EUC for I/O stream.

NOTES
When you use jconv8 with jconvrs(7M) or jconvru(7M) at once and `raw' is specified by stty(1), code convert function automatically become
off without specification by EUC_OXLON / EUC_OXLOFF. By default, character set indication escape sequences as follows. The end character
may be changed by JA_SKIOC.
o ASCII indication: ESC 2/8 4/10
o Character indication: ESC 2/4 4/2
o Convert with JIS X 0201 Kana: LS1/LS0
jconv8 does not support Kanji code for Information Interchange (secondary kanji set) provided by JIS X 0212-1990.
When jconv8 is in use, csh(1) does not work properly for filename additional function.
