Hi Mario,

I use Teraterm daily at work, and I found this post from a while back
that may help you.  If you are using an old version of Teraterm, you
might want to snatch up this newer version.  I think it is just what you
need.  HTH!

Since I just posted a long ranting request for help, I figured I better
balance that with a nice long solution-oriented write-up.
 
I saw this question on various screen access lists. People want to know
which terminal emulator works best with JAWS, or how to access some
Unix-Linux-BSD with JFW or simply how to use a terminal program in
Windows with screen access.
 
I feel particularly sorry for the blind student who is trying to take
some sort of Unix course, and not only has to figure out this new OS but
needs to figure out how to access it while simultaneously using the
college's Windows computers. Usually the access technology specialists
don't have a clue, or the information on the net is incomplete, outdated
and/or
inaccurate.   
 
I run several Linux machines, and am fortunate enough to have access to
many old computers which need terminals to talk to them.  I have
researched this a lot, and have tried many telnet clients,
hyperterminal, secure CRT, Kermit for Windows and Putty. By far, my
favorite application for accessing remote computers with JAWS is
TeraTerm.
 
First, grab yourself a copy of the latest UTF-8 TeraTerm Pro 4.60. Many
older  versions are floating around, but I guarantee that 4.60 works
great with JAWS. I've used versions 5-10 of  JFW with 4.x versions of
TeraTerm.
 
The TeraTerm site is: 

 <http://ttssh2.sourceforge.jp/>     http://ttssh2.sourceforge.jp/   
 
other urls you might encounter contain dated versions.   
 
Install the program and say No to all the extra little tray applets.
They don't do any harm but who wants resource hogs that aren't needed.
If you get one by mistake, standard techniques, like using msconfig can
make it go bye-bye.  If you do accept all the defaults, the install will
add these unwanted extras. They keep unnecessary windows open but will
not adversely
affect your computer's accessibility.   
Next, if you have JAWS, a version later than 5,and you want TeraTerm to
automatically speak while text scrolls (like a console window) create
this
script:   
 
Include "HJConst.jsh"  
 
Void Function SayNonHighlightedText (handle hwnd, string buffer)  
 
var  
 
string TheClass  
 
let TheClass=GetWindowClass(hWnd)  
 
If GetScreenEcho () > ECHO_NONE && TheClass == "VTWin32" Then  
 
    Say (buffer, OT_NONHIGHLIGHTED_SCREEN_TEXT);  
 
endif  
 
EndFunction  
 
this script should be specific to TeraTerm, it should be called
"ttermpro.jss" and you should *NOT* put this code in the default script.
 
If this is all Greek to you don't worry. You can skip this scripting
step and TeraTerm will still work fine with JFW. Without the script, you
will need to use your JAWS cursor or virtualize the window, or a Braille
display to read incoming data. At work I use Braille and the JAWS
cursor; at home, I use the script. Both techniques work, and I switch
between them each day.
 
You will find several, far more elaborate TeraTerm scripts out there.
You don't need them. Many were for older versions of Tera Term, and
older versions of JAWS.

One old script disables my semicolon key, and another of these outdated
scripts makes my Braille display constantly jump around. 
 
A script very similar to mine above was originally on  the blog of Saqib
Shaikh, which seems to be no longer on the net. I'd like to give him
credit for the idea, and I only plagiarize because I can't find his blog
to link you to it.  
 
Anyway, this code is simply what gets executed in a Win32 console window
(what used to be called a DOS box)  when the user chooses to have
highlighted text spoken but actually wants to have new text read as it
comes
onscreen. It's stolen from part of the JAWS default script.   But in the
default script, the code executes only for console windows, not for the
TeraTerm window.
 
The situation for a terminal user is similar to a DOS box user; they
don't actually want highlighted text, they want all new text, but not to
hear old text read more than once. In other words, when the text
scrolls, causing new text to be written and old text to be rewritten as
part of the scroll operation, the JAWS user wants to only hear anything
new, and not a repeat of the old text.  
 
For DOS screen access, this was easy. These programs simply read video
memory when users were not working with scrolling applications. When
they were, the DOS screen reader filtered calls to the PC BIOS. The BIOS
handled the scrolling and the screen access program never saw the old
text again. so the user never heard old text repeated. In DOS, the
screen reader watched the text that was sent to the BIOS screen
services, so it knew about everything sent to the screen through the
BIOS. Video memory only had to be consulted if a program wrote directly
to the screen. Because DOS terminal programs usually had the BIOS handle
their scrolling, they for the most part worked great with screen access.
  
Anyway, with Windows, lots of behind-the-scenes magic goes in to
building the off-screen model: the screen reader's best guess about
what's onscreen now. I only half understand all that magic.  
 
I do understand that often it's hard to tell the difference between old
text, that's simply scrolling and new text that's just arriving.  
 
But this script does a great job in console windows and works fine in
TeraTerm most of the time. You do have to adjust some TeraTerm settings.
You must disable the scroll buffer, verify that there are only 24 lines
of text
onscreen, and set the cursor shape to horizontal line.   
 
When TeraTerm first loads, you are invited to create a new connection by
filling in some fields. You could tab through these or scroll down a
list of available connections.  but instead, follow these steps:
 
1. Press ESC to make the connection window and list go away.
 
2. Press Alt-S to pull down the Setup Menu. Press W to open the Window
setting dialog.
 
3. Press Alt-O to move to the cursor shape dialog box.
 
4. Press down arrow twice to select Horizontal line. If the cursor shape
is vertical line or block, JAWS *WILL NOT*  track the cursor.
 
5. Press S to select the check box for the scroll buffer. By default it
is checked,  so press space to uncheck it. If the scroll buffer is
active, the Braille display will jump around, and focus won't always be
accurately tracked.
 
6. Press Enter to activate OK. The setup screen disappears.
 
7. Press Alt-S to call up Setup again.
 
8. Press T for the Terminal settings dialog.
9.     Here you should tab through the fields making necessary changes.
The
default terminal size is 90 columns by 35 rows. You want 80 columns by
24 rows.  Your host system should also be set to match -- more on that
below.
Also ensure that the terminal ID is set to vt100. Press Enter to
activate OK.
 
10.  Press Alt-S again to activate settings. Then press S  to Save them.
Press Enter to accept the default of Teraterm.ini.
 
Here we get to what I like best about TeraTerm, this .ini file It is
ASCII text and very easy to edit. As you get more experience, you can
create .ini files for the different hosts you connect to.  Then you can
create shortcuts that launch Teraterm with that particular .ini file and
automatically log you in to that host. For example, Truffle, my Linux PC
at work, is easy to connect to with the command line:
    "C:\Program Files\teraterm\ttermpro.exe" truffle.blah-blah-blah.edu
/f=truffle.ini
 
I created the truffle.ini file myself. The -f parameter to use a
different settings .ini was buried in the TeraTerm documentation.
 
My thanks to Darrell of the blind access journal for the original steps.
I've expanded them slightly as my experience grew.
 
Darrell's blog and the JFWLite tips and tricks page also suggests you
download some scripts that didn't work for me. They were the ones that
disabled my semicolon key! I'm pretty sure they used to work
and that something's changed with JAWS that makes them unnecessary.
Or
maybe TeraTerm changed, or the author of the scripts never needed his
semicolon! Anyway, those scripts went in to my bit bucket!
 
There will be times you won't want everything read aloud. For example,
this happens when using most editors. You can just use Insert-S to set
JAWS for no automatic speech, and go back to saying highlighted text
when you want
scrolling text to be automatically read again.   
 
And if you wish to permanently turn off automatic reading, simply rename
or move my script. Or don't use it at all.
 
In TeraTerm, JAWS properly tracks the cursor while editing in vi, emacs,
Joe and nano.  I don't know other editors so this is all I've used. I've
connected using ssh, telnet and directly to a computer with a serial
port.
TeraTerm is a MDI application so I can connect to different computers in
different windows. I've happily used it with several Unix variants,
including all flavors of BSD and ultrix. I've used it fine with a VAX,
but if you have problems, remember for Vaxen you need to change your
delete key to do a backspace.  
 
To copy and paste, it's easies to use the virtual cursor -- press
Ctrl-Insert-W or define a keystroke to do it that's easier to press.
You can then copy text from the virtual buffer.  I also use this
technique to reread information onscreen since I find it easier than
using the JAWS cursor. If I get to something I want to copy I can easily
do so.
 
To paste in TeraTerm the keystroke is Alt-V. I find it trivial to copy
and paste between online documentation and the system I'm communicating
with. I also often copy and paste between systems.
 
There's one additional issue with TeraTerm. Occasionally something in
Ncurses causes TeraTerm to display euro and other garbled symbols,
instead of line drawing characters. It's a problem for sighted users
just as much as screen access users. I've reported it on the TeraTerm
support forum, and you can read that forum at:  
 
 <http://www.neocom.ca/forum/index.php>
http://www.neocom.ca/forum/index.php  
 
Several sighted people have confirmed that indeed, this  is a problem.
It happens only when ncurses applications are running on the host, for
example, a program that uses a cursor and highlighting and sometimes
reverse video and multiple pseudo-windows to simulate the look of a
graphical application. The Ubuntu/Debian aptitude is a good example. I
encounter it most when using
dpkg-configure.   
 
When I do have to work with a ncurses app that's behaving badly with
Teraterm, I've used putty (another free terminal emulator and ssh
client) but JAWS does not correctly track the Putty cursor. JAWS always
is off by one character.
 
Another solution with TeraTerm is to fool with terminal types, possibly
setting it to VT320, and setting your host to Vt100. This is most
definitely not a JAWS bug, and it is just an annoyance to hear unwanted
symbols being read.  I have had success sometimes faking the terminal
type, and working around it by changing locales. If you are not the
administrator of the host system, for example you are a student, you can
confidently show the messed-up screen to sighted people, because the bug
is as visible as it is audible!
 
A couple more tips: if TeraTerm's screen updates are being missed by
JAWS, maximize the window, switch focus away from it and then back, and
do Insert-Escape to force the JFW screen-model  refresh.  Double-check
that JFW is tracking properly in Notepad, because sometimes it just
needs to be completely restarted.
  
Also,  if automatic reading gets really really screwed up, clear your
screen by first telling the host to clear its screen if possible, then
in TeraTerm, clearing the screen and the buffer with alt-E S for screen
and alt-E b for buffer. Both these commands are on that alt-E edit menu.
And at most Unix shell prompts you can type
    clear
 
to force the Unix to clear its screen.
 
And a few quick notes about host systems. By default, many use a
terminal type of xterm, which works great with the TeraTerm defaults but
not with JFW, especially if you want to use Braille. Even if you use
speech, it's often easier to work with a smaller screen, and certainly
an xterm can scroll whereas a Vt100 cannot. In Linux, the default
terminal is named Linux, and that causes visual and occasional JFW
problems for the TeraTerm user.
 
On most Unix systems at a shell prompt type export TERM=vt100
 
to fix the host. If you are a student, get your system administrator to
permanently change your login account so vt100 is always your terminal
tuype. If TeraTerm settings were properly adjusted and you log in to a
system and JFW cannot track the focus the problem more often than not is
the system, and not JAWS.
 
Be aware that many applications might use highlighting or reverse video
instead of a cursor which is harder for a screen access user to track.
You often have to figure out how the application can be made to use a
real cursor. For example with the web browser lynx type
    lynx -show_cursor
 
If you are a beginner, explain to your helper that your screen reader
needs a real cursor to track and have them comb through the
application's documentation. Unlike Windows, most applications on
systems accessed by terminals have some way of using a real cursor. This
is because some terminals will not correctly display highlighting or
reverse video. However it's often hard to figure out where their
configuration files live and what variables to change. The only solution
is to TRIM which stands for "Read the Fine Manual!"

Subject: [JAWS-Users] Tera term and Jaws 10

Hi,

I have to manage a linux server, a couple of years hago I had used
Teraterm with a set of Jaws scripts for the 5th version of Jaws. Now I
will want to use a client that allow me to read the system answers
automatically without using the Jaws cursor, but the scripts for
teraterm ovviously doesn't function correctly. Are there some scripts
for teraterm for Jaws 10? Or I can use another client? I've tryed putty,
but Jaws isn't responding correctly.

Thanks in advance.

A presto,
Mario Loreti
