I'm not sure what you mean by "enable a modem connection".
You might have an interrupt conflict on whatever interrupt the card

A voice modem CAN handle incoming calls like an answering machine with
the correct software. This does not mean you can use the modem and
phone at the same time. Each option voice/fax/modem is mutually
exclusive (i.e. one at a time).

Well, I don't know to what degree Linux supports the Posix.4 real time
extensions, but here is what it would look like if it did (all
information taken from "Posix.4 Programming for the Real World", written
by Bill O. GallMeister, published by O`Reilly)
#include <time.h>
struct timespec current_time;
(void) clock_gettime(CLOCK_REALTIME,¤t_time);
The timspec structure appears as:
struct timespec {
time_t tv_sec; // Seconds in interval
long tv_nsec; // nanoseconds in interval
}
Also, as a footnote in the book (1995 issue) reads "The current
generation of SPARC boxes, for instance, supports two timers, each of
which can resolve time down to a granularity of 500 nanoseconds. That's
pretty fine, but SGI's top of the line offers a sporty 21-nanosecond
resolution!".
Anybody know to what degree Linux supports Posix.4?
I also dimly remember somebody developing a real time operating system
that would run Linux as a client, but allow it to talk to and interact
with the real time kernal. Not a bad idea, kind of like a client server
arrangement with two operating systems on the same box.

Is there a FAQ on this somewhere? I've never heard of this proprietary
USR interface before (unless you're talking about parallel port
modems, and I thought those really didn't take off all that well).

Maybe I was vague. I did use netcfg from the controlpanel to initially set
up eth0. When I enabled it the system completely locked up. I had to do a
power cycle, and from then on, until I removed the ifcfg-eth0 script, the
system locked every time the card was inserted.

I meant that, again, when I used netcfg to create a ppp0 interface on
/dev/modem, nothing happens. This is of secondary interest at the moment.
I realize there are a lot of things I could be doing wrong here like
/dev/modem pointing to the wrong com port, etc.

Wouldn't an interrupt conflict show up as soon as the card's inserted? If I
don't enable any of the interfaces, the card is recognized, and id'ed
correctly. I haven't had time to get another look at everything.

Date: Thu, 20 May 1999 19:54:20 GMT
Well, after a bit of wrestling, I got Bttv and xawtv compiled ok... I
get a picture, but no sound.. My best guess is that this is because
the sound chip on the card is not compatible. I have attempted to
identify the sound chip by searching the card with a magnifying glass
and penlight, but no luck.
I am using an ensonique Audio PCI sound card (1371).
Some of you other folks out there have the Avermedia TVphone Tuner..
(Mine is not the '98' version)... have you had luck getting sound?
What is the workaround?
Thanks,

Thats normally a cabling problem between the card and the monitor, as in
too long, and too cheap. I don't think the card is doing it *unless*
there is also a pattern of horizontal lines indicating the monitor is
out of synch.

I want to build a Linux box that fits in a small case that I can stick
out of the way, stuck in a corner somewhere. It will be left on 24x7,
so I like it to be quiet and consume as little power as possible. It
will contain a CD-ROM drive and 1 large EIDE drive. A motherboard
with onboard video and Ethernet would be desirable. Finally, I'd like
to keep the price to around $400. Any recommendations?

2 buttons, the others just don't respond. I am using it with snes9x and
it is irritating to have to use the keyboard whenever a particular

something called a "4 button patch" for the driver and I thought this

Subject: Installing RH 6.0 on preexisting partitions.
Date: Thu, 20 May 1999 16:48:36 -0500
Hello,
Hopefully someone can help out a Linux newbie here. I am running a
multiple boot system on a Fujitsu 6.4 Gb IDE hard drive and a Western
Digital 4.3 Gb IDE hard drive. On the 6.4, I have as Primary
partitions, OS/2's Boot Manager (7 Mb), Win98 (2047 Mb/Hidden C:), OS/2
Warp 4.0 (3271 Mb/Hidden C:), and 855 Mb of free space for Linux, in
that order. On the 4.3 Gb, I have 2 2000 Mb logical partitions D: and E:
with 94 Mb left over for Linux Swap. In case anyone needs to know, this
is a Pentium Pro 200/512 running on an Acer v60n motherboard, Intel
440FX chipset. I have tried to install RH Linux 5.0 and 5.1 on this
system before, by creating a Primary partition with OS/2's fdisk, then
changing the type to linux native with linux fdisk. No matter where I
place the partition for linux, from the very first partition on the
drive to second and so on, LILO will not install. I install linux
packages just fine, either with a full blown install, or with a minimal
18Mb install, but when I get to the Install Bootloader part, linux will
not install either on the MBR, or first sector of boot partition
(preferred). I have not tried to make a linux boot disk to see if that
will work, since I would much rather prefer to find a way to get my
existing setup to work. I am able to move around the partitions
wherever they need to be to get this to work, but I would like to try
and avoid a complete format/restore if possible. Any help would be
greatly appreciated.
Thanks,
Aaron W. Bayles
