problems starting remote speech server

["T. V. Raman" <ramantv@xxxxxxxxxxx>]

What you are seeing is  potentially caused by more than one
instance of Outloud trying to speak at the same time.

    RAYNER> desktop-machine 2222 It replies with connecting

    RAYNER> 2222
    RAYNER> /usr/share/emacs/site-lisp/emacspeak/servers/outloud
    RAYNER> Hmm, not so good.  And my tcp-wrapper log

    RAYNER> To try to shed some light on this I started the

    RAYNER> but then, in an rlogin window on target-machine
    RAYNER> tried telnet desktop-machine 2222 which produced

    RAYNER> couldn't open device /dev/dsp2: No such file or
    RAYNER> directory couldn't open any sound device
    RAYNER> Connection closed by foreign host.

    RAYNER> and the same segmentation fault message back on
    RAYNER> desktop-machine.  Among other curious questions
    RAYNER> is why the outloud speech server is trying to
    RAYNER> open the sound devices when launched from the
    RAYNER> speech-server tcl script but not from the rsh
    RAYNER> command.  As usual with this kind of apparently
    RAYNER> subtle problem, I'm probably overlooking
    RAYNER> something *really* basic.  btw: this is
    RAYNER> happening with emacspeak-12.0 running under
    RAYNER> emacs 20.4.1 on RH6.2.  target-machine is
    RAYNER> running emacspeak-12.0 under emacs 20.3.3 on
    RAYNER> irix 6.5.

    RAYNER> Once someone has pointed out my oversight, I've
    RAYNER> got one more question.  I'd like to launch
    RAYNER> emacspeak straight into this remote connection
    RAYNER> method the same way I am with the rsh method.
    RAYNER> At the moment I have things set up to run
    RAYNER> emacspeak-setup before my .emacs file, so I get
    RAYNER> immediate feedback on things like the diary.  Is
    RAYNER> there something I can set to tell emacspeak not
    RAYNER> to bother with local speech-servers and just
    RAYNER> execute emacspeak-remote-connect-to-server
    RAYNER> Raman, if this doesn't exist and you think it
    RAYNER> would be useful, I'm willing to try to hack it
    RAYNER> in.  Phew, quite a long message, apologies.
