Control s does not work

Control s does not work

I'm very new to emacs, and trying to fix a customers problem.  The
forward search, cntl s does not do anything.   Only in some cases, the
other cntl sequences I use will work like C-x C-c, and C-r for reverse
search.   Other cases, the terminal is hung and I cannot break from it.
This happens accessing the system with putty, CDE, gnome, as root, or as
another account.  This happens on solaris 8 and 9, but the systems in
question are RHEL 3 updt 4 with GNU Emacs 21.3.1  On this redhat system,
the C-r, C-x, C-c will work, but not C-s.
Thanks!

This will not solve your problem, but i suppose it's the expected
behaviour on a terminal (the hang i mean) as Ctrl-s is usually bind to
the stop character (IIRC Ctrl-q should be the start character).

Here, with, zsh it's disabled using "unsetopt flowcontrol", but i've
done it only to have in the shell a working "history incremental
search forward" when i use Ctrl-s. From what i recall, it has never
been a problem when using Emacs...

This is a FAQ, see:

  http://sunsite.ualberta.ca/Documentation/Gnu/emacs-21.1/html_chapter/faq_10.html#SEC139

Which raises another question: why is the Emacs FAQ not on gnu.org
with the rest of the documentation? Yes, I know, I should probably
file a bug report... 8;-)

Anselm

Because it now comes with Emacs itself?

Btw, the Emacs FAQ _is_ on gnu.org, you somehow missed it:

   http://www.gnu.org/software/emacs/emacs-faq.text

Hm, I expected to find a link to some HTML-formatted version here:

  http://www.gnu.org/software/emacs/manual/

since this listing looks a lot like the Emacs section in the my info
directory, just lacking the Emacs FAQ. And: of course I prefer info,
it's just easier to point newbies to the web. 8-)

Anselm

The Emacs FAQ is not part of the manual, it's a separate Texinfo
document.

RE: Control s does not work -- thanks for the input on this

[Lamont, Brian-p3354c]

I set the command stty -ixon on the linux system the customer said it
didn't work on, and it did not fix it.  The customer ran stty -ixon on
the "host" he launched from and it worked.

The customer telnets in to "host" as his userid, then uses Powerbroker
to connect to the linux systems.  It appears the "host" needed to have
the flow control turned off so as to not pass the cntl s flow-control
characters to the linux systems. 

Thanks for all the responses!!!  Guess I didn't look hard enough. ;-(


Thank you,
Brian

I know. But on

  http://www.gnu.org/software/emacs/manual/

you find all the other Emacs-related documents (like Dired-X, Ediff,
Gnus, Tramp, ...), all of them from separate Texinfo sources IIUC. So
why not the Emacs FAQ, then?

I don't know.  Something to write to the GNU webmasters about, I'd
think.
