Process speaker not running?

My reply to this last week was terse because I was away at WWW97.

Let me try and explain what I think is happening in your istuation; it's
basically the result of
misunderstanding how the various emacspeak environment variables work.

Here is a summary:

Emacspeak uses three environment variables.

a) DTK_TCL --pathname to a tcl interpreter
(or in general an interpreter that will be called with a synthesizer specific

b)  DTK_PROGRAM --the name of the device specific script e.g. dtk-exp

c) DTK_PORT --port where the speech box is connected e.g. /dev/ttyS0

Upon startup, Emacspeak launches the driver by executing
DTK_TCL with DTK_PROGRAM as the first (and only) command line argument.
The above is expected to examine environment variable DTK_PORT to decide where
the speech device is connected; if that environment variable is not set it
picks a suitable platform default,
e.g. /dev/ttyS0 on linux or /dev/ttya on sparcs.

With this summary, it's probably clear why things went wrong for you.

2) Killing a hung emacs, and getting minimal spoken feedback from a shell:

This is not really an Emacspeak question/answer, but you may find what I use
useful for your own situation.

1) In your /usr/local/bin create a simple
shell script called speak that sends its arguments to the speech box ie a
talking version of the shell's echo.

Assuming you use bash:

b) In your .profile, add a command at the end to echo a message to the speech
box indicating succesful login.

c) bash lets you specify a command to execute every time a shell prompt is
I have a sound card so I typically set bash to play a sound file like so:

(replace play and ding.au with appropriate pathnames for your setup.
If you dont have a sound card, set PROMPT_COMMAND to something like
echo "go. " > /dev/ttyS0
d)  Now, if you are stuck, you can go to another virtual console, and get
sufficient feedback to do what you need in terms of killing a stuck emacs, or

I typically have shell scripts called "spot" and "slay"
that accept a process name, e.g. emacs and display the pid --
so to locate an emacs session I would do
bash: spot emacs

and to get the output spoken
speak `spot emacs`

note that the above backquote trick is really useful when you have no other
e.g. you can tell which directory you are in by typing
speak `pwd`

Finally I also typically have a script called slay that nukes processes by
name so I can do
slay emacs
once I have detected the offending process with spot do
kill pid

Hope this helps alleviate some of your frustration--
