readline doesn't obey 'set bell-style visible'

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040207 Firefox/0.8 Description of problem: The file /etc/inputrc (or another file indicated by INPUTRC) contains readline commands read at invocation. I regularly add: set bell-style visible Since the audible bell annoys me... as was apparently Chet's wish: <http://lists.gnu.org/archive/html/bug-bash/2001-02/msg00023.html> In RHEL4 beta1, the bell is still audible although 'bind -v' indicates that readline is set correctly. Changing the command to 'set bell-style none' correctly disables the function, but I prefer the visible bell. Version-Release number of selected component (if applicable): readline-4.3-13 How reproducible: Always Steps to Reproduce: 1. echo 'set bell-style visible' >> /etc/inputrc 2. bind -f /etc/inputrc && bind -v # to verify 3. Tab-complete something (bTABTAB) and note audible bell Actual Results: Bell is still audible. Expected Results: Bell should be only visible. Additional info:
The same can be seen from running 'python' and pressing backspace. This must be a libtermcap or termcap problem I think. (TERM was 'xterm' for my test -- although 'linux' works with no problem with bell-style visible.)
libtermcap does not read /etc/inputrc. libtermcap reads /etc/termcap. Not each terminal/terminal-emulator is able to 'beep' or 'flash' or 'beep' and 'flash' (this is a terminal-capability, terminal-capabilities are described in termcap or/and terminfo-database). For more info launch at the command prompt: man 3 beep (beep() is ncurses-function, libncurses reads terminfo-database). You cannot 'add new' terminal/terminal-emualtor feature by modifying any config-file. Therefore it cannot be 'a bug' in libtermcap or /etc/termcap. In other words: if your current terminal-emulator does not beep/flash, you cannot change this (you must modify terminal-emulator-source and then 'add new capability' into termcap/terminfo). On the other hand, there can be a possible bug in redline-library but this is not a bug in libtermcap/terminfo.
