Hi guys,
I'm about to need to write a program that requires me to call a phone
number and play a message. I don't know where to start.
Is there a modem library for linux. How do you build a route from your
sound card to your modem and stuff like that. Is there a book I could
get?
Thanks

Hi!
I need to write a program the will call a number and play a message.
I need to find out how to connect to the modem, put the modem in voice
mode, route the sound card to the modem and play the message. I will
also need to modem to keep the line open for DTMF after the connection
is made.
Where can I start, is there a linux book on com programming? Or program
that already does that. Can I make the initial connection using chat?
Pleae help me

Subject: GA-7ZX Onboard Sound Problem
Date: Thu, 19 Apr 2001 19:59:43 GMT
I'm using RH6.2 and have installed it on a GA-7ZX with a Duron 800.
When configuring sound with sndconfig it autodetects Ensoniq:CT5880. But
when it goes to play the sample sound the system locks up.
/etc/conf.modules has the following inserted: alias sound-slot-0 es1371
Reading other post with similar issues I changed it to the following: alias
char-major-14 es1371 with no success.
I even tried modprobe with different arguments; es1371, char-major-14
es1371, es1370 just to see what will happen, but still no success.
Is this a 6.2 issue, would upgrading fix it?
Any help would be greatly appreciated.

I read somewhere that the Z52 Linux driver from the Lexmark homepage can be

get it to work?
Any info would be appreciated.

Ok, I won't say it... I'm sure someone else will :-P.
try checking out http://www.linmodem.org (or something like that)... I've
heard there is nominal support for some of the chips, but not all.
IMHO - get a real modem, let the modem due to the work, save your cpu for
interesting stuff, like games :-)

You can get U3-160 solutions for the *same* price: well, ok,
about $500 more. So, how exactly is that price/performance?
Pricey performance perhaps :) I'll respond about the XOR stuff
when I get a chance, I am a little busy at the moment.

Excuse me? Did you see the specs? 640GB of raw disk space. The
cheapest price for a 73GB, U160 drive on pricewatch is $900. 8 of those
those runs you $7200, already $1200 greater than my entire system, and gets
you 56GB less raw space. And you still have to buy the chassis (which,
for my system, cost $3300). So you're looking at *at least* $4500 more.
I'd really like to know where you got your numbers.
I'll leave some of the quoted material below, for the specs.

Subject: Logitech wireless wheel mouse
Date: 19 Apr 2001 15:26:19 -0700
Reply-To: [EMAIL PROTECTED] (Warren Jones)
Has anyone succeeded in getting the wheel to work on a Logitech
wireless wheel mouse? I'm using XFree86 4.0, imwheel, and these
entries in XF86Config:
Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "Device" "/dev/mouse"
Option "Protocol" "MouseManPlusPS/2"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"
EndSection
This has worked for me with other wheel mice (Kensington, Microsoft),
but although the buttons of the Logitech mouse all work correctly,
the wheel does nothing. (The side button acts like another middle
button.)
I've seen suggestions that the Logitech wireless mouse uses
a somewhat different protocol, which may not be understood
by XFree86. Has anyone had any luck in getting the wheel
to work?
Thanks in advance for any tips,

Typically, this is caused by your kernel sources (/usr/src/linux)
being "too clean". :)
You have to do a "make menuconfig" (or something similar) in the
source tree of the linux kernel.

Now that is funny - I love it when the best come back a unix-nut has is:
until you've suffered as I've suffered and continue to suffer you are
nothing. The fact you can do what I can do in 1/4 the time with 1/8th the
effort means you _obviously_ must be an idiot and I am a genius for slaving
away working on much bigger and more compliated proprietary hardware.
as if run time had anything to do with throughput - silly...

There's got to be a bus that connects everything.
Even if you can swap out one-by-one all the hard
drives, all the RAM, all the I/O stuff, individual
processors, and so on, at some point there's going
to be a piece that ties it all together, the bus
if you will. Unless it's highly modular, you
won't be able to swap out that part with the
system running.
Also the power supply could be a problem, unless
it has multiple redundant power supplies.

You *could* store each cached page as a database entry.
Or you could use the filesystem as a database, which is
what most caches do (with a special file for the index).
It doesn't really matter which.

Zero *user-noticeable* difference. The exact numbers don't
matter, because the difference will come out in milliseconds.
The user won't be able to tell without special time-measuring
software like a benchmark. Whether it's a thousandth of a
second or a tenth of a second is immateriel (and, in any
case, very much hardware-dependent).
Furthermore, there's absolutely no point in a cache that
large. Pages you visit so seldom that they aren't stored
in a ten-megabyte cache aren't worth caching, because the
chances are really good you'll NEVER visit them again.
(Note that I'm talking about a browser cache. A caching
proxy is another matter entirely.)

Bigger than a browser cache ever needs to be.

Noticeable by the user.

Because the existing caches are sufficient. The time you
perceive that it takes to find a page in the cache
consists almost entirely of the time the browser spends
doing *other things*, such as loading the page after it
finds it (which is limited by the hard drive's transfer
rate), comparing its cached copy to the copy on the
web, rendering it for display, repainting the window,
and so on.
