No such luck.
A Voice/Fax/Data modem is a Digital Signal Processer.

The Voice part lets you use your modme/computer as an answering machine
(with the correct software)

If you want to be able to use phone and the modem at the same time then
you will need to get a different kind of phone line.

The two best candidates are ADSL (fast but limited areas)
and ISDN.  Call your phone company and ask.

Hi

I am running Linux 5.2 on an IBM Thinkpad 560.

Will I have problems come Y2K???

Anyway to find out?

Subject: USB Scanner, Whare do I start?

I checked through all my /doc using recursive grep,
but I don't see anything helpful on getting my USB
supported.  I did get referred to USB.org, but that
was less than useless.

Could someone give me a hint on where to start so I
can use my Umax USB Scanner inder Linux?

I hate having to boot into that lesser operating system.


Don't reply by mail.  As an antispam measure I am

By the way, is it true that because users spend so much

You need to run mkinitrd program to create a new initrd image.  If you bought Official 
RH 5.2,
this is on page 200 of the manual.  It talks about scsi drivers, but should work for 
NICs as
well.

No. The P5A is a Super Socket 7 board and would need something like
a K6-2.  Plus it's harder to get UDMA support out of the ALI
chipset.  The Asus P2B is a good Slot 1 mobo for Celeron and P-II.

But for good quality and less $$ check out the AOpen boards, for
example:

  AX59Pro - Super 7
  AX6BC   - Slot 1
  MX3L    - PPGA Celerons

honnestly I doubt that you'll be able to get to less than 1 microsecond
resolution.  You may have already found the UTIME
project at http://hegel.ittc.ukans.edu/projects/utime/, but it claims to
give a precision of only 50us.  and although it is a cool idea make sure
you look at the "known bugs" section and teh fast timers part.  I think
your best bet is to use the time stamp counter which was already mentioned
somewhere.

Hmmm.  I've been searching in this question for the past few weeks. here is
what I've gathered (from newsgroups, web, etc)

_POSIX_REALTIME_SIGNALS
_POSIX_PRIORITY_SCHEDULING
_POSIX_MEMLOCK
_POSIX_MEMLOCK_RANGE
_RANGE  _POSIX_MAPPED
_FILES _POSIX_MEMORY_PROTECTION
_POSIX_TIMERS (not implemented)
_POSIX_ASYNCHRONOUS_IO
_POSIX_PRIORITIZED_IO (not implemented)
_POSIX_SYNCHRONIZED_IO
_POSIX_FSYNC
_POSIX_MESSAGE_PASSING (not implemented)
_POSIX_SEMAPHORES (hmm. partially implemented)
_POSIX_SHARED_MEMORY_OBJECTS (not implemented)

this is all supported either by the kernel 2.2.x or by glibc-2.1, it's not
counting any patches you might find (my impression is that they are all
wrappers to alredy existing  functioality). if anyone has any corrections
or info what's comming please email me.  my impression is that there aren't
even plans for anythign that's marked as not implemented.

I think there's a patch for the i740 chipset.  I have one on my Mandrake CD, so
I'm sure there's got to be one floating around somewhere.  If you can't find
it, let me know, and I'll shoot it to ya...maybe it'll help.
One thing I have noticed also is that AGP seems to be best supported by the 3d
XF86Setup.  I recommend going to www.xxedgexx.com and seeing what they have
there.  I was having the same probs with my Creative 3D Banshee card, but after
getting these packs, I'm able to run at just about any res. I want.  (3d not
supported yet, but I'm working on it.)

OSS is the Open Sound System
It's a commercial but easy way to get sound working on Linux
The free version nags every twenty minutes, but it works with
all kinds of cards.

I *think* the address is www.opensound.com

Good Luck!

I did a little poking around on my ISP account (who is smart enough to
be using Linux) and found out (from the man page for nanosleep):

BUGS
       The current implementation of nanosleep is  based  on  the
       normal  kernel  timer mechanism, which has a resolution of
       1/HZ s (i.e, 10 ms on Linux/i386 and 1 ms on Linux/Alpha).
       Therefore, nanosleep pauses always for at least the speci-
       fied time, however it can take up to  10  ms  longer  than
       specified  until  the  process becomes runnable again. For
       the same reason, the value returned in case of a delivered
       signal  in *rem is usually rounded to the next larger mul-
       tiple of 1/HZ s.


Sounds like on a PC, 10 ms is the best you can do and remain platform
independent.

Subject: Help! Sound Loop Error with Crystal CS34232 Sound Card!
Date: 21 May 1999 09:53:38 GMT

I have spent *weeks* trying to get my sound card configured correctly for my
system, all with very little success.  My latest problem is that regardless of
the application I use, whenever I play a sound file, a one second clip of it
plays, and repeats over and over and over again, until I finally stop it.

I don't understand.  I have been able to edit my isapnp.conf file such that
there are no listed resource conflicts upon inititialization.  However, when I
set the IRQ to 5, I get an error message saying that that IRQ is already
occupied.  However, when I do a "cat /proc/interrupts/", it indicates that the
sound device that I'm configuring is what's using that IRQ, and hence it would
seem that there is no conflict at all.  Also, I'm not able to clear that IRQ,
nor am I able to remove the sound modules and re-initialize them.  My system
tells me that "sound is in use", although no sound applications are listed as
open (at least, none that I recognize as sound apps).

Please help me!  I have spent more time than you can imagine trying to figure
this out, and no answers.  It's extremely frustrating!  All I want is to have
functional sound on my machine!  It's not as though I'm asking for much here.

If you have any possible solutions, please respond, and CC your reply to my
address.  Thank you.
