>Anybody know how I can redirect the beep to my speakers? I miss > the confirmation that vi/vim puts out. Outside of X, our kbdcontrol(1) offers pitch and duration (but not volume) control for the console bell via the -b flag. The volume is often dependent upon the hardware and/or the bios, and in some cases cannot be easily changed. Unfortunately, our keyboard-handling code does not seem to allow the remapping of individual keys to strings -- I think that can be done in Linux -- so we can't add a bel to every keypress by defining an alternative keymap via kbdcontrol, without hacking the code (but since ed@ is working on a new console driver, this might be a good time to request features...). However, at a slightly higher level, many shells and editors will allow you to rebind keys. And some will allow you to redefine the action taken when the bell is sounded: for instance, out csh(1) has the nifty "beepcmd". You could customize this to play a sound file of your own choice through your sound card, where you presumably have more control over the sound, and then try to use bindkey to issue bels with keypresses. Of course, this will only take effect while you're in that shell or editor, but you could use the idea to hack the syscons(4) driver to redefine sc_bell() if a certain sysctl is set... b. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

But, like the '03 computer, the beep is too soft to do any good. Somehow, my Ubuntu desktop has the vim beep working thru the powered speakers on my Thinkpad. But the xset click simply does not work.

You can determine it easily: If you plug something into the sound card in order to mute the built-in speakers, and you still hear a sound, it's a "real" speaker besides the sound card's speakers. If you don't hear anything, all audio output - sound card AND PC speaker - is done by the built-in speakers. > Anybody know how I can redirect the beep to my speakers? I miss > the confirmation that vi/vim puts out. Early sound cards (e. g. the Logitech SoundMan 16) had an option to "copy" PC speaker output to the sound card output, even allowing to set the volume of this channel (treated like any other channel, e. g. CD, PCM, MIDI). > Probably help to be a dog! --That reminds me of what my parents > generation were saying about mine [with its loud music].

The kind of beep that is emitted (e. g. via BEL) doesn't seem to be adjustable.

It seems to be determined by hardware. > Should be a way to send the beep to my desktop speakers, then, > right? I've got volume and power, treble/bass.

On early 386 PCs where there was a real "powerful" speaker inside the box, I created a headphone out by removing the speaker and replacing it by a 3.5mm jack, so I could attach earphones. A program I wrote could output waveform data through the PC speaker (in absence of a real sound card), so this was a kind of "do it yourself soundcard". Imagine the fun of connecting a PA. :-) > This older computer was high end in 2003 > but I don't remember seeing a real speaker, so if it's some IC > that's producing the 'beep', I'm outta luck. In "modern" PCs, the speaker is often replaced by a kind of micro-speaker, a black cylindrical object with 0.5mm radius and a small hole in its top. It's a kind of piezo-speaker, sufficient for a friendly little "Beep!" at boot time. The development of recent PCs, as well as of notebooks and netbooks, makes me think that there won't be a speaker (a physical one) in the future anymore. On some systems, e. g. a Siemens-Fujitsu notebook I own, the speaker's functionality is given by the "sound card" and through its speakers, but the control for the speaker is still the "traditional" way. Maybe this way - simply sending 0x07 / BEL, or something like /dev/speaker implements - won't be possible in the future... This will force the output of any sounds through the "sound card" (or its representation by the chip"set" respectively), requiring a specific driver to access the particular hardware. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

You can do quite a lot with various tempos, intervals and frequencies; see speaker(4) and play around. Making a short click or thunk! should be easy enough, but spkrtest and echoing playstrings >/dev/speaker are userland processes; I've no idea how much 'fun' it would be to invoke /dev/speaker ioctls from the kbd drivers.

I work the same way, but I even apply the step of validating the HTML code through W3C validator. I would appreciate an urge to web developers to code valid HTML. And web browsers should implement it. Then all the scary non-HTML pages could not be viewable anymore, the browser shows nothing, or gives an error message: "The page you're intending to view does not contain valid HTML and cannot be displayed.

East/west? whatever? Of course. First off all, basic education in the eastern part (GDR) is still a bit better due to better teachers who are still on duty. In the western part (FRG), education is worse, basically. Then, there are differences between the federal countries. There's no common educational concept. Schools are organized differently (different layers, different names, different degrees), "horizontally" and "vertically". Degrees are not comparable inside Germany, so for example when you leave Gymnasium (high school) in Hamburg, you can join a university in Hamburg, but you cannot join a university in Munich because it doesn't recognize your degree from Hamburg. There are no common teaching plans. If you move from Leipzig to Hannover, you're doomed. The GDR didn't have those problems. Teaching plans were the same in every school. Same plans, same books, same "speed". Results were comparable. Sweden has adopted the unified GDR educational system, with success. In the FRG, education selects the future of the children by the income of their parents. If you have rich parents, you can affort to go to Gymnasium (high school, 13 years) and go to university later on. If your parents are poor, e. g. unemployed, you have to go to Hauptschule (main school, 8 years), and maybe Realschule (real school, 10 years), but you cannot go to university with such a degree. You will even have major problems finding a professional education in order to get a job. The levels of "how good" schools are considered in society have lowered through the years. In approx. 1995, Gymnasium was "over-qualified", Realschule was "ideal for a very good job" and Hauptschule was "good for a normal job". 10 years later, in approx. 2005, everything was shifted <<, with Hauptschule now "just for a helper job", e. g. carrying sand bags on a building site. Today, this is what Real- schule was, again shifted <<, and Hauptschule is the direct way to unemployment after school. > And how does GErmany stack up compared to the rest of the EU? Quite bad. The reason is simple: Basal knowledge isn't taught in schools anymore. After 8 or 10 years, there are still massive deficites in reading and basic calculating. Other copuntries in the EU are already recognizing the development and are investigating about how to improve the educational system. The FRG, of course, can't do that. Today's educational system is the same as of Kaiser's and Hitler's time. So it CANNOT BE CHANGED. Period. A good comparison is Japan or China. The first stages of education are quite "frontal". Basic things are repeated until you can rely on them. Later on, there's no repeatition anymore. And why? Because it isn't needed. Pupils and teachers can rely on their presence. The GDR had the concept of the Kindergarten, which prepared children for school, equipping them with basic knowledge and some handcrafting skills. > And the States. I always considered the States to have not a very good educational system (this is due to how Americans are precepted here, especially on TV), but it has one advantage which I consider very modern: It gives you the right NOT to send your kids to a public school (where they have to wear weapons and are slapped into the face by classmates if they don't hand

On my PC I hear the 'bell' from the PC > speaker, but no clicks. Blow me away! Is there a version of xset without X11? Or: how do I get X up on my server? I.e.: what do I need to compile it and launch to get, say, twm up? I bought the loudest old-fashioned clicky keyboard (for like $80) and it's beautifully loud. Tactile Plus auditory feedback. It is beyond outstanding. But to bring this along with some notebook would not be practical. I can barely hear my desktop's beep when I have mail, so can't hear anything when I do % xset c 100 .
