Communicating with USB Modem

[Hal Vaughan]

I have a Debian Lenny system and I've plugged in a USB 56K modem.  (I know 
that's as outdated as a Model T, but I need it for business.)  When I type "cat 
/proc/bus/usb/devices" I get this:

From what I can find, that means the actual device file for this modem should 
be at /dev/bus/usb/001/002, but I know I could be wrong on that.

I'm trying to communicate with this modem.  I've used Minicom, with the device 
I mentioned above.  There are no /dev/ttyACM0 devices, as sometimes happens 
with a modem.  I've tried all /dev/ttySx, where x is from 0 to 4, with no 
results.  The problem with Minicom is that it can take time and a lot of 
frustrating keypresses to try one device after another.  Also, I'm not sure the 
serial port speed settings are at all appropriate in Minicom for USB modems.

I was also trying a Perl program that would simply fork, have the parent open 
the device for reading and listen, then the child would open the same device 
for writing and send "ATZ" through to the device, then I could watch for a 
response -- but then when I tried it on a system with a serial port where I 
knew the device was /dev/ttyS0, it didn't work, so maybe there's a problem with 
the program.  (I don't want to post a full Perl program here, since this isn't 
a Perl board that focuses on debugging Perl.)

This is a test situation, so I can't be sure the modem works with Linux, but I 
would think if it's external and USB, it would have to accept serial commands 
sent over the USB port.  I could be wrong on this, of course.

So here's the questions:

1) What device should I be able to write to and read from to connect to this 
modem?

2) Any suggestions on how to write to and read from the device?  (Write to it 
in Perl or use echo in bash -- but then how do I read to see results?)

3) Any other ideas or suggestions on how to control and use this modem in Linux 
(without going into C or C++)?


Thanks for any help on this!

Anything in dmesg or syslog when you plug it in?

From  (the Linux Documentation

2.9 USB Modems

USB = Universal Serial Bus. Most USB modems are winmodems, so many will
not work...

Unless, of course, you know that this particular device should work with
Linux.

Then you can follow the recommended steps to getting additional 
information about the crash:

5.4. Troubleshooting the Installation Process
http://d-i.alioth.debian.org/manual/en.i386/ch05s04.html#submit-bug

Or you can try with another medium. Network images or CD, for example.

you need to be aware that it may NOT always be F7-F8.. right now mine is F8 & 
F11.. I was F7, but I logged out, logged in guest as F9, logged me in/out & 
ended up me being F11..
I was trying to recall there was supposed to be a command that allowed it to

but either it didn't work, or I did it wrong..

Howto add autostartup applications

[Johan]

Good day,

On the internet I was informed to use update-rc.d.

According the man page..:
EXAMPLES
  Insert links using the defaults:
 update-rc.d foobar defaults

This is what I get..:

unknown001e33032a68:/home/johan# whereis gkrellm
gkrellm: /usr/bin/gkrellm /usr/share/man/man1/gkrellm.1.gz

update-rc.d: /etc/init.d/gkrellm: file does not exist

unknown001e33032a68:/home/johan#

Please what is wrong.
Thanks

That is not suitable for programs that run as normal user. It is meant
only for programs that are specifically meant to be run in the background.

Are you using GNOME?

For starting "gkrellm" when booting? :-?

Applications are not services. 

You can launch "gkrellm" by going to "system → prefs → sessions → 
startup" and adding a new entry that points to the binary "/usr/bin/
gkrellm".

If you are using another desktop different than GNOME your mileage may 
vary.

As Ron suggested, better look at dmesg messages.

- If the device is not detected, it will (not) be there.

- If the device is detected but has problems for being setup, it will be 
there.

- If the device is properly detected and configured, it will also be 
there.

USB modems should fall under "/dev/ttyUSB0"

Don't go nuts with this. Just plug the modem, open a console, type "dmesg 
| grep -i usb" and put the result here (for very long logs, upload the 
result to "www.pastebin.com" or any service like that) :-)

a data rate threshold tool?

[Zhang Weiwu]

Hello. I found my application, which was supposed to run 10 hours,
either run and starve every other service on it, or doesn't run at all.
Even with nice and ionice, I cannot avoid other web services starved by
this application. And it has to run on the production server.

One trick that comes to my mind is to use a data rate threshold tool to
limit the data rate input is fed to the application.

$ threshold --rate 20KB/s < data_source | my_greedy_application

Is there such a tool in Debian?

Thanks. Running Debian 5.

I will not filled a bug report because this is a weekly version. So, I
hope that in the next week it is covered.

I bypass this problem starting the installation with a old version
(2009) and add the newest dvd when prompted me.

I have a little problem with GRUB2, because old version use GRUB 0.9.
I bypass it in part (UUII problem).

I install the minimal system and now I am searching a workaround to
put my Atheros wireless up. I need wpasupplicant and all deps (I am
looking for a way to download all deps together). I will try to modify
/etc/network/interfaces. My AP use wpa2 passphrase. This issues is
welcome because it is an opportunity to upgrade my knowledge. :)

Thank you very much!

A good weekend!

Please tell us exactly what your application does, what you mean by
"data rate", and what your "data_source" is.  It sounds like the problem

I don't know about a tool, but assuming it's not important that the rate
is precise as long as it's somewhere about right, a simple perl script
will do it. You can probably do similar things with python etc.

The following takes a rate in bytes a second and optionally a block size
in bytes, and writes a block of data at the appropriate interval (no
--rate - so if you save it as "threshold" invoke it as threshold 20480
  - for 20kB/s). Default block size is 1k. Note that I only just wrote
it, so YMMV and take it as an example for experimentation ;) Should be
fairly obvious how it works; note it'll do silly things if you give it
silly arguments, in particular very large block sizes.

-- start of script

#!/usr/bin/perl

use strict;
use warnings;

use Time::HiRes qw(sleep);

my $rate=$ARGV[0];
if(!$rate) {
   print STDERR "No rate given\n";
   exit 1;
}

my $block_sz=$ARGV[1];
$block_sz=1024 unless $block_sz;

my $delay=$block_sz/$rate;

my $bytes;
my $nbytes;
while($nbytes=sysread STDIN, $bytes, $block_sz) {
   while($nbytes) {
 my $wbytes=syswrite STDOUT, $bytes, $nbytes;
 if(!defined($wbytes)) {
   print STDERR "error writing: $!\n";
   exit 1;
 }
 $nbytes-=$wbytes;
   }
   sleep($delay);
}

if(!defined($nbytes)) {
   print STDERR "error reading: $!\n";
   exit 1;
}

exit 0;

Re: Disable IPv6

Just a quick question - can I disable IPv6 for my whole machine?

"
You can disable IPv6 system-wide by editing your module configuration
file. This is usually one of /etc/modprobe.conf or
/etc/modprobe.d/aliases, depending on your distro. Remove any references
to IPv6 and add these two lines.

alias net-pf-10 off
alias ipv6 off
"

Is that going to do the job fine for lenny?

>>>

What is your distro, your kernel?
For lenny's kernel 2.6.26 you can include the file ipv6.conf into the
directory /etc/modprobe.d with the next content:
blacklist ipv6
For the next versions of kernel (i.e. 2.6.32) you can include the words
"ipv6.disable=1" into /boot/grub/menu.lst such as the next:
kernel  /boot/vmlinuz-2.6.32-bpo.5-amd64
root=UUID=x ipv6.disable=1 ro
Or compile your own kernel without ipv6 from sources.



OK so do I have a choice here? I can change /etc/modprobe.d/aliases and I can 
change /etc/modprobe.d/ipv6.conf


In /etc/modprobe.d/aliases there is a header with the warning

"
# Please file a bug against module-init-tools if a package needs a entry
# in this file.
"

I'm just about to reboot now so if I'm lucky this will be my only question - 
hopefully it won't break anything. I can't think of anything I'm running that I 
know needs IPv6.

There's no /dev/ttyUSB0.  Just the usual /dev/tty and the same with 0-63 on the 
end and /dev/ttyS0 through S3.  I tried all of them and all the possible USB 
devices in that directory.

That's what I have now:

NO CARRIER

Failed

In /tmp/q I have:
"" atd*#06#

Seems that my modem wants a carrier for something - that gives me a

mine. But thank You for the point of using chat. I did read that

There you got it. It's an Agere soft modem.

Bufff... as per this doc¹ you could try "sl-modem" package from non-free 
repo (it seems that your device -SV92U2- uses the "Scorpio" chipset) but 
prepare for the worst ;-(

OTOH, LSI (the owner company of Agere) states that the modem supports Linux, 
so you can ask them for a driver :-?

How to change jpg time stamp using exiv2

[Ken Heard]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

According to the exiv2 man page the command to change a jpg time stamp
is as follows:

exiv2 -a  adjust 

 is the difference between the time to be adjusted and the new
time in the format [-]HH[:MM[:SS]]. For example: 1 adds one hour, 1:01
adds one hour and one minute, -0:00:30 subtracts 30 seconds.

So, I have a time stamp of 2010-04-16 Fri 07:11, where I want to change
the time to 19:11.  So I run

exiv2 -a 12 adjust img_1234.jpg

and get the following in return:

Warning: Makernote IFD has a next pointer != 0 (128). Ignored.

So the man page is obviously wrong.  I would appreciate it if someone
could tell me the proper format for this command.

Hi,
I newer used exiv2, tried for first time with your command "exiv2 -a 12 
adjust" on my_photo.TIF and everything was ok.
"exiv2 -u my_photo.TIF" give a difference before and after "exiv2 -a 12 
adjust" in image timestamp.

Moving Debian installation to another partition.

[Roman Khomasuridze]

Hello kind people.

The story is, that I want to install FreeBSD on my computer, but
unfortunately i don't have spare primary partition (only logical one), and
as freBSD documentation says, I can only install it on primary partition, so
I'm thinking to move my current Debian installatin from primary partiion to
logical one.

here is my fdisk -l


/dev/sda1   *   1261020964793+   7  HPFS/NTFS
/dev/sda226113656 8401995   83  Linux
/dev/sda336573899 1951897+  82  Linux swap / Solaris
/dev/sda43900   38913   281249924+   5  Extended
/dev/sda539004872 7815591   83  Linux
/dev/sda64873   38913   273434301   83  Linux

Debian is on dev/sda2, i'm moving it to /dev/sda5

After some research and thinking(!), my plan is to do following steps:

1. mount /dev/sda5 /mnt
2. cp -ax /* /mnt
3. modify /mnt/boot/grub/menu.lst
4. modify /mnt/etc/fstab

So, am I missing something? Will these four steps be enough?
My current Debian install is approx 2 years old, and I don't want to screw
it up.

Any suggestions are greatly appreciated, and thanks in advance!!



Regards

Roman

Wouldn't putting a .desktop file in ~/.config/autostart serve to make
the program autostart on _any_ XDG-compliant system? That's what I'm
getting from reading the spec (though it's marked Draft currently)

I had a reference, and now I can't find the darned link, to it working on 
Linux, otherwise I wouldn't have bought it -- unless I had a bunch of tabs open 
when I was researching modems at Newegg and hit "add to cart" on the wrong one 
-- which could happen.

I can't remember where (so it could have been the manufacturer's site), but 
there was one place I read that if it's USB, it had to use the Hayes command 
set and would work on anything, but Brad's link to TLDP shows that wrong.  Next 
time when I see positives on something like that, I'll look for the flip side, 
just in case.

I've already ordered one from NewEgg that has several reviewers saying they're 
using it on Linux.


Thanks!

And that is _exactly_ what you get by following the instructions I

DE like GNOME).

To be fair, that link mentions the usual state of things, and I did
qualify it by saying something along the lines of "unless you know this
one does work with Linux".

A quick Google found this;
, which states the the
modem does indeed run under Linux.  However, in the (brief) time I
searched, I couldn't find any links to the driver itself.

I can give you at least one reference (the manufacture's tech. specs):

***
http://www.agere.com/docs/PCS_Catalog_052606.pdf

(page 5)

– SV92U2: USB 2.0 device controller, 48-pin TQFP Stack Bus

(...)

OS support: Win98SE/2000/ME, WinXP, WinXP 64-bit, Vista (Native Support), 
and Linux
***

If that is indeed your device, don't give up so easily :-) Just try with 
"sl-modem" drivers or ask LSI/Agere for advice, it could work.

When it comes to modems and linux, the only way to hit the right device 
is by using a RS-232 modem. No drivers needed and straight-forward setup 
for all kind of services (dial-up connection, fax facility...).

Yes, yes... I know. Serial port is a scarce resource in modern 
motherboards and n[eo]tbook computers ;-(

  There are a number of free public resources available from the 
US National Institute of Standards and Technology.  A former
employer of mine used Special Publication 800-53 as a baseline 
for a security policy.

  Besides providing a list of recommendations, it also has a 
pretty good discussions of the "whys" behind them, and the
cost-benefit trade-offs that must be made.
 
  A list of NIST security division's publications is here:

Squeeze here, and sounds can be enabled (see linked snapshot):

http://picpaste.com/sounds-rHbtyPAw.png

Hint: try to force-load using gconf editor:

/desktop/gnome/sound/[x] event_sounds

Anyway, I hear no system sounds even I've enabled that setting (and relogin).

Moreover, I can only get sound when running this command as root user:

r...@debian:~# canberra-gtk-play -f  /usr/share/sounds/ekiga/ring.wav

And it plays the "ring", but running the same as plain user, I get:

t...@debian:~$ canberra-gtk-play -f  /usr/share/sounds/ekiga/ring.wav
Failed to play sound: File or data not found

:-?

I see that, the one thing that is discouraging me is that, while I know they 
are talking about the chip, the pictures are of PCI modems, not the USB ones,

I tried the page you linked to, which had a link to the site with drivers, but 
that 2nd site is all blank web pages -- still looking for the sl-modem drivers. 
 Did I miss a link?  That's possible.  (The dead link is: 
http://www.smlink.com/.  It's from the last paragraph of that page, the only 
section that covers Linux there.)

A little backstory here.  My small business mines data, and a lot comes from 
some dial-up systems where you can get passwords, but most people ignore them 
now since they're harder to deal with (therefore, if you're bigger, less 
lucrative, if you're smaller, good money).  I have a US Robotics RS-232 running 
on the main system now and I have another that was brand new, that I pulled out 
and tested, then put back in the box.  I guard those modems carefully.  They 
work and I know they work.

But an idea hit me this summer.  I haven't been programming in about 3 years 
(I'm a screenwriter by passion, so I've been doing that).  This idea that hit 
me would take several months of programming and it'd be a game-changer for me 
in terms of income from the data mining.  But to do it, I have to decentralize, 
which means instead of having one computer here doing dial-up, I'd have to put 
a computer in each client's office and have it do dial-up there.  I won't get 
into all the reasons and thinking behind what I'm doing, but, in short, I want 
what's in their offices to be as simple as possible and to be a black box.  I 
do not want them hooking up a keyboard or monitor to it ever.  I don't even 
want them to think of it as a computer, EVER!  So I'm looking not at low end as 
in cheap, but as in saving money and still getting a good embedded system.  
Each system will need a modem and I'll keep backups (of the computer and modem) 
on hand, ready to ship when needed.

I have used a USB-to-RS-232 converter with success for a FOSS project to 
control an HD radio (http://halblog.com/hdradiocontroller.html), but an RS-232 
modem is more expensive and the converters are expensive, too, putting the 
price per modem well over $50 each.

I've ordered a Rosewill that looks good.  It costs more than the one I have 
now.  I'm going to try any drivers I can find for this one, but considering the 
price of the other one, with shipping, is $30, if the drivers don't work and 
the manufacturer doesn't help, I'm not going to knock myself out over this one. 
 I can always use it on a Windows machine and use that system for testing (to 
have my other ones dial in).

As it is, though, considering how cheap these are (this one and the replacement 
people have tried on Ubuntu), I think spending more than a few hours

IMVHO, I think at least part of the speed increase is based on the fact

I have managed grub and mbr for dual boots of Debian, have not used the -ax' 
method for moving an install.

Have a plan for managing grub, changing grub.menu.lst  you will still need 
to 'update-grub' to have the changes propagated to the mbr or wherever you plan 
to have it.

Decide which OS manages the boot loader, this will determine whether to install 
grub to mbr or partition.

 I don't know what BSD uses for a boot manager but being able to 
run  'update-grub' from Debian after the BSD install will add BSD to  Debians 
grub menu.

Re: Moving Debian installation to another partition.

[Roman Khomasuridze]

Thanks for reply..

well, I'm not planning to touch MBR, GRUB, or whatever, my main goal at this
stage is to move Debian system from one partition to another safely,
 without issues.
Also, second question raised, after moving Debian to another partition (thus
moving menu.lst), won't GRUB fail to load? Will 'update-grub' be enough, or
will I need to reinstall it?

Oops, sorry. I thought I already told you "sl-modem" drivers are

I see... It's quite difficult to keep the track of manufacturers making 
cheap and linux friendly devices. One has to perform a big search in the 
web (reading forums, mailing lists, asking users to get accurate 
feedback...) to find out what USB modems (chipsets) play fine with linux 
distributions.

O.k. I also think geting an USB modem to work should just be plug and 
play and no needing to mess with drivers at all. But it could worst: 
there are some embedded modem

Yeah, I missed it.  When I start researching, I look at everything, then as I 
focus on some parts, I am not as good about making sure I read all of it.  Oops!

I found that just after writing my last email on this thread, but just before I 
had to leave to take my Mother to "night out" meal - didn't have time to add in 
that I had found it.  Thanks.  The issue, though, is that needs another 
package, one that's not a dependency, it's "sl-modem-modules-2.6.26-2-686".  
I'm looking, can even find it in a package pole, but can't find the package 
itself.

Yes, it is.  I am seriously considering, when I get the right modem and know 
things are lined up and am starting production of the new system, to just order 
20-30 of whatever I find.  I'll just eat the cost then and make it up as I 
deploy them.  I don't want to find the right modem, order 3-4, then find it not 
in production anymore.  Again, I'd go with RS-232, but the expense is greater 
and, honestly, when they're going in someone else's office, so I have to be 
sure I can ssh in (which is a project in itself, considering different offices 
and different sysadmins), I have to be aware I will NOT have hands-on access.  
It sounds picky, but using an adaptor on a plug in such a case is just another 
thing that can go wrong and that I could spend hours trouble shooting to find 
some oaf jarred it and there's a loose connection.  The fewer the connections 
and the simpler the system, the more time I get to spend ballroom dancing 
instead of patching software.  (I'm a believer in setting up a system, then 
letting it do the work while I don't!)

Pdf Font hardly legible

[Memnon Anon]

Hi,

I've been using xpdf for a looong time, and I never had a problem,
except that it can be a bit slow on my old machine.

So today, I tested evince and epdfview, but some pdfs (all from the same
source) which are perfectly fine in xpdf are hardly legible. 

,
| mem...@mymachine:~/pdf$ pdffonts -f 3 xyz.pdf 
| name type  emb sub uni object ID
|  - --- --- --- -
| Times-Bold   Type 1no  no  no   8  0
`

I suspect that this font is not available to evince and epdfview and so
it chooses a "bad" alternative instead. Installing the msttcorefonts
(br) did not help, either.

However, I know that lots of you people do not use xpdf, and I think
there should be a remedy.

Any advice is very much appreciated.

Memnon

Of the open source PDF viewers, Okular (formerly Kpdf) is the best
overall . But Evince has a better export to PostScript and is more
lightweight. I don't mind using closed source apps as long as they're
free, so I use Adobe Reader a lot as well. There was a recent upgrade
of Adobe Reader to 9.4. Among other closed source tools I also have
Cabaret and Foxit Reader, all running natively on Linux x86_64.

Lightweight is what I need. My machine is an "old" P3 1.2 Ghz with
"only" 512 MB Ram. I tried Adobe Reader once, but it was *really* heavy;
it was ridiculous: this machine suffices for everything I do, but
reading a text 100 pages long with Adobe Reader made it feel sluggish.

Pdf has its benefits, but I really don't understand why displaying text
has to freak out my notebook more than basically anything else I am
doing, even with xpdf :(

I was connecting by dialup only for about three years until recently.
I agree that RS-232 hardware modems are good.

But there is also a new breed of external USB modems that works just
as easily. The one I bought was US Robotics. It was plug and play, no
additional driver needed.

I bought that modem because the computer that used it did not have
a serial port.

I'm not sure why your udev rules aren't firing, but, shouldn't you be
umounting the filesystem *Before* removing the drive? Your udev "remove"

like you would be risking a corrupted filesystem by umounting an
already removed drive.

I prefer to use a combination of udev rules and automount to handle
removable media, since I generally avoid using desktop managers.

I had an external USB modem that was initially very gratifying, to
use with a computer that had no serial port. I plugged it in, the
system found it, and I was online in minutes. No external drivers.
It was a very nice experience after having spent many hours trying
to get drivers to work for WinModem cards.

The one I used was US Robotics, but I can't lay my hand on it right
this minute to say the product number.

I did have some problems with this modem over time. The main thing
I remember is it would get moved from /dev/ttyUSB0 to /dev/ttyUSB1
occasionally. Or sometimes when the machine was booted the device
wouldn't get established. I don't know if these were problems with
the modem or my system.

I wanted to point out that the modem I had initially seemed very good
because of how easy installation was. But that's not the whole story.
And that there are some plug and play USB modems out there.

I do basically everything with
Emacs/Ratpoison/Conkeror/mplayer.

Irc/Jabber with bitlbee+erc, surfing with Conkeror, Mail+News with gnus,
latex with auctex ...

Nothing brings this machine down like a large or complex pdf.

pdftotext is not really a solution.

I guess I will add some more ram soon. 

Funny, I used to say: "Hey, I need to update my machine: Doom 2 is too
slow!" and it made sense. Now, its: "Uh, I need to upgrade, viewing 3
papers at the same time for my theses is too slow?!". 

I wish jstor.org offered download as plain text or html, but at least
its not doc :).

I would think, ideally, a good modem would be like that -- as long as it 
responds to AT commands properly, then it wouldn't need a driver.

I saw some USR USB modems, but considering how I'll be buying a number of 
these, and footing the price myself (for various reasons, I can't really pass 
along this cost to my clients), if the $25 modem I ordered works, I'll be using 
it over the $45-$50 USR modems.  It's pricing.  Now if they're flaky, then, 
yes, I'll spend more, but if they work, I won't.

That's a USB issue.  I ran into that when I was writing my code for controlling 
the Visteon HD radio (I have a copy of the project on my blog, but the main 
reason I did it was to turn it over so LinuxICE would have a radio controller). 
 I had to write a routine that would first check the config file and look for 
the radio in its last place, then, if needed, send the same signal to every USB 
device and look for the response.  The only issue is that I was worried the 
wake-up signal for the radio might crash some devices.  I can't remember why I 
didn't just scan /proc/bus/usb/devices to get the info.  I think I had to scan 
the /dev/ttySx devices.  While the radio would USUALLY be at the same place it 
was last time, sometimes it would move.

I think, for modems, plug and play means that it simply responds to the Hayes 
command set through a device in /dev.  I'm not sure what you'd set the serial 
bus speed for in a program like minicom, though.

Look into mupdf - a really lightweight PDF reader.

I downloaded the tar.gz file and untarred it, but could not figure out
how to install it. There is no .deb or .rpm file in the archive.

Note: I want to install it on a computer that I use for DTP which runs
Fedora 11, not Debian like my other computer. It is not in the Fedora
11 repositories.

basically , the you can  uncompress the tar.gz file and
cd to the directory  ./configure &&make &&make install .
of course maybe the dependency is not solved automatically .

you should read the README file first .

I agree that you should go with the cheapest one that works as expected.
I don't mean to imply that US Robotics USB modems are better than any
other one, just mentioning that it worked for me. US Robotics had a good
reputation around hardware modems, but then they made WinModems, and
now these USB modems are a breed apart from either of those two. Now
their reputation is ?

I bet part of what you get for $47 from USR is their name brand, and
maybe a RMA policy or warrantee. But if a Rosewill behaves the same, I
doubt the hardware will be much different or more flaky. I'm out on a
limb here, though, because I haven't actually tested different brands
or looked at the hardware.
