YKH v1.2.2 Copyright (c)1993 Bryan McNett

Thank you for taking a look at YKH, a freeware Japanese VT320
emulator for DOS! I hope that you find YKH as useful as I have.
I am sorry that YKH does not have many of the features people have
come to expect in terminal software, such as phonebooks or file
transfers. I would like to implement these features, time permitting.
If you have any questions or comments, please feel free to write me

revision history:
Version 1.2.2 properly displays kanji; version 1.2.1 did not. (sorry!)
new command-line options and an .INI file also appear first in this
version.
Versions previous to 1.2.1 loaded the entire kanji font into unused
video planes so that no kanji caching mechanism would be necessary.
Well, this turned out to be a dumb idea. As soon as I installed MEMMAKER
on my machine, YKH's kanji began to appear scrambled and broken up.
So I spent a few hours rewriting the kanji display routines, and now they do
use a cache, and do work with MEMMAKER.

YKH overview
YKH is a program for DOS that emulates a VT320 terminal while properly
displaying Japanese text. It is able to connect via modem through comports
1 and 2, or over local-area networks using the DECNET LAT and DECNET CTERM
network terminal protocols. Unlike most Japanese terminals, YKH is able
to fix Japanese text that has been damaged by escape-code stripping.
The terms of YKH's distribution are described in GNUGPL.TXT.
---------
requirements
YKH requires at least an 80286 CPU, the extended keyboard BIOS, a VGA
graphics adapter, and about 128K of free RAM.
---------
how to install YKH
To install YKH, copy the files YKH.EXE, YKH.INI, and JIS.16 into one of
the directories in your PATH. If the file JIS.16 is absent from the directory
that YKH.EXE is in, YKH will run, but it will not be able to display Japanese
text. Note that YKH runs much faster when not displaying Japanese text.
---------
the file YKH.INI
YKH.INI, like the .INI files used by Microsoft Windows applications, contains
information and default values that remain the same between YKH sessions.
When YKH is run, it searches in the current directory for YKH.INI, and
if it cannot find it there, it searches in the directory where YKH.EXE
resides. The structure of the YKH.INI file is as follows:
[section]
item=value
item=value
[section]
item=value
and here are the various sections and items currently in use by YKH:
[Ports]
port
the port used to communicate with the host computer. can be com1, com2,
lat, or cterm. lat and cterm are DECNET network terminal interfaces,
and can be used to login to networked systems running DECNET.
defaults to com1.
service
the DECNET node name of the system you intend to login to using the lat
or cterm terminal interfaces. generally, a six-letter word.
no default value.
[Modem]
baudrate
the baudrate at which YKH should communicate with your modem.
generally set to 300,1200,2400,4800, or 9600. defaults to 2400.
databits
the number of bits per byte used to hold information. defaults to 8.
stopbits
the number of bits per byte used as stop bits. defaults to 1.
parity
can be none, even or odd. defaults to none.
[Kanji Fonts]
font16
full pathname to file containing the shapes of kanji characters. If an
incomplete pathname is specified, the current directory will be
searched, and then the directory where the executable file YKH.EXE
resides will be searched.
YKH's kanji file is in the same format as JIS.16 used by the word processor
NJSTAR, so it is possible to keep one copy of this file on your hard drive
for both YKH and NJSTAR to use. defaults to JIS.16.
---------
command-line options
Most of the options that you can set in YKH.INI can be overridden if
specified on the command-line. Here is a list of command-line options
used by YKH:
(any option may begin with either a - or a / character)
-p[1|2|c|l] com port # or network terminal port name (l for lat, c for cterm)
-sXXXXXX DECNET node name you wish to connect to
-d# # databits
-P[n|o|e] none, odd, or even parity
-S# # stopbits
-b# baudrate of # bps
-h
-? list command-line options
---------
dialing your modem from within YKH
Once you have run YKH with the correct settings, you must dial your
modem manually with the keyboard. For most modems, this means typing
ATDT, followed by the number you wish to dial, and then hitting the
Enter key. For example, to dial the number 555-1212, you could type
this line:
ATDT5551212
Consult your modem's manual if this does not work.
---------
how to exit YKH
You can exit YKH at any time by pressing Ctrl+F10.
---------
how to enter kana into YKH
It is possible to enter kana directly into YKH, even though your keyboard
does not have kana. YKH has three keyboard input modes: roumaji,
hiragana, and katakana, which can be selected with the F5, F6, and F7
keys, respectively. When you are in roumaji mode, your terminal responds
to your keystrokes in much the same way a VT320 would. When you are in
hiragana or katakana mode, everything you type is converted from roumaji
to kana, and then displayed on the top line of the screen. When you are
finished typing a string of kana, hit the Enter key. This will send the
kana string to the host computer in the "new-jis" format, and then
return you to roumaji input mode.
To abort sending the kana string you have just typed, hit the Esc key.
You will be returned to roumaji input mode.
This is a clumsy system that is not very useful. I wrote it into YKH
only so that I could use Jim Breen's "xjdic" program on the workstation in
my office from my dorm room.
A future version of YKH will include kana->kanji lookup, which is
arguably very useful when one is trying to enter Japanese text.
---------
how to switch between EUC and SJIS modes in YKH
Most of the Japanese text encountered on computers will be in the New-JIS
or Old-JIS formats, which YKH is able to detect and display correctly in all
circumstances. There are other Japanese text formats, however, that YKH is
unable to distinguish between. The EUC and Shift-JIS formats overlap, so
there is no simple way for YKH to determine if Japanese characters are
in one or the other. For this reason, YKH allows you to choose which format
you'd like to use. Pressing the F8 key switches between EUC mode, in which
EUC and SJIS text is displayed as EUC text, and SJIS mode, in which EUC
and SJIS text is displayed as SJIS text. An indicator at the upper left hand
corner of the screen tells you which mode YKH is currently in.
---------
how to use YKH with host systems that garble Japanese text
If you are trying to look at what you have been told is Japanese text,
and it looks something like this instead:
$@F|K\8l(J
chances are that the system you have connected to is not transmitting
the escape codes that let most Japanese terminals know when to display
Japanese text. "news" and the VMS operating system are common culprits.
YKH provides a simple solution to this problem. Hitting the F4 key toggles
"fix" mode, in which YKH inserts escape codes into garbled Japanese text in
an attempt to display it co
