[New package] Drivers for Lucent LT Winmodem

I uploaded the modules for the Lucent LT Winmodem in incoming.
Here's the PKGBUILD :

pkgname=ltmodem
pkgver=8.26
pkgrel=1
pkgdesc="Modules for the Lucent LT Winmodem (PCI), compiled for the 2.6.8.1 kernel "
url="http://linmodems.technion.ac.il"
license=""
depends=()
makedepends=('bash' 'sed')
conflicts=()
replaces=()
backup=()
install=
source=(http://linmodems.technion.ac.il/packages/ltmodem/kernel-2.6/ltmodem-2.6-alk-v00.tar.gz)
md5sums=(c219d9d62034da24c1543f3c4bce1c91)

build() {
  cd $startdir/src/ltmodem-2.6-alk
# Configure

  VERSION=$(uname -r)
  SCRIPT=$(echo 's/2.6/'$VERSION'/g')
  SOURCE=$startdir/pkg/usr/src/ltmodem
  MODULE=$startdir/pkg/lib/modules/$VERSION/ltmodem
  FILE=$startdir/src/ltmodem-2.6-alk/Makefile.tmp
  sed  -e "$SCRIPT" < $startdir/src/ltmodem-2.6-alk/Makefile > $FILE
  mv $FILE $startdir/src/ltmodem-2.6-alk/Makefile
  FILE=$startdir/src/ltmodem-2.6-alk/serial.c.tmp
  sed  -e 's/save_flags(/local_save_flags(/g;s/restore_flags(/local_irq_restore(/g' < $startdir/src/ltmodem-2.6-alk/serial.c > $FILE
  mv $FILE $startdir/src/ltmodem-2.6-alk/serial.c
# Make
  make || return 1
# Install
  if [ ! -d $SOURCE ] ; then
    mkdir -p $SOURCE
  fi
  cp Makefile linuxif.h *.c ltmdmobj.o $SOURCE
  cp $startdir/README $SOURCE
  if [ ! -d $MODULE ] ; then
    mkdir -p $MODULE
  fi
  cp ltmodem.ko ltserial.ko $MODULE
}

I also included a README to help with the configuration:

This README file briefly explain how to set up your system for the
Lucent Microelectronics LT Winmodem (PCI) modules.

To check if your modem is supported, you can use the lspci command or
use the scanModem utility which can be downloaded at:
"http://linmodems.technion.ac.il/packages/scanModem.gz".  The scanModem
should only be unpacked in a Linux partition because corruption by
hardstops occurs in Microsoft partitions.

1. Install ltmodem with pacman

2. Create a character special file

        mknod --mode=0604 /dev/ttyLT0 c 62 64

3. In /etc/modprobe.conf add:
        alias char-major-62  ltserial
        alias /dev/modem     ltserial

4. In /etc/rc.conf, add:
        ppp_generic ltserial ltmodem
        to the MODULES line

5. You can set a link to the device.  With udev, add
        KERNEL="ttyLT0", SYMLINK="modem"
   to /etc/udev/rules.d/00-myrules.rules

If pppd quits with an ERROR 1 just after connection, try commenting
auth in /etc/ppp/options or use the call option (see manpage).

Let me know any comments, bugs, etc.

Re: [New package] Drivers for Lucent LT Winmodem

I registered my package at http://bliss-solutions.org/archlinux/incoming/
but I couldn't login to ftp://ftp.archlinux.org.  I tried with an anonymous login and my email address but it didn't work.

Re: [New package] Drivers for Lucent LT Winmodem

hi
the package looks good so far
one tip/suggestion
it would be possible to make the package kernel independent
that's better for the maintainter and user
pacman -S ltmodem would rebuild the module for an updated kernel and you needn't to release a new package or the user need to recompile it on his own
have a look at my intel 536/537 modem package in staging
add your readme to the PKGBUILD as info in a install file
let the module build in the install file too
look at my example if you like
http://xentac.net/tur/tags/staging/intel-537/

just some thoughts
bye

Re: [New package] Drivers for Lucent LT Winmodem

I prefer packages that are (at the binary package level) kernel dependent.  I am not a fan of meta-packages.

Re: [New package] Drivers for Lucent LT Winmodem

tpowa,

I will look at your exemple.  It is possible that I make some minor change ( maybe doing a daemon, using  one of the standard directory instead of creating the ltmodem ones, etc.). 

However, from comments in the code/makefile, it seems that the drivers only work for 2.6.nn kernels now due to some modification in the code.   I think that the modification is a commented line but that  will need to be tested.

Re: [New package] Drivers for Lucent LT Winmodem

i prefer meta packages
because i have not always time to keep up with kernel updates and this way it's not a problem
and it runs on most setups :-)

Re: [New package] Drivers for Lucent LT Winmodem

But pacman doesn't know about the files, it won't work in all cases, and you can't install the drivers for two seperate kernels (say 2.4 and 2.6, both stock) at the same time.

Saving the packager from doing gis* job also isn't a good excuse.  You have a responsibilty to ensure that your packages work, which is a broader definition than just "it installs and runs".

Meta packages are ok when they have to happen, but should not be used with reckless abandon.  That's why things like srcpac were created.

*gis is the third person singular possessive determiner that Dusty proposed we use to stay gender neutral.  ge is the third person singular pronoun.

Re: [New package] Drivers for Lucent LT Winmodem

gis * ... learned something new :-)
yep i see your point
i think i change my package back to kernel dependent
i forgot that we have srcpack

Re: [New package] Drivers for Lucent LT Winmodem

I uploaded a new release in incoming on ftp.archlinux.org (ltmodem-8.26-2.tar.bz2).
Here's my new PKGBUILD:

# Contributor: Eric Belanger <belanger@astro.umontreal.ca>

pkgname=ltmodem

build() {
  cd $startdir/src/ltmodem-2.6-alk
# Paching Makefile and code
  VERSION=$(uname -r)
  SCRIPT=$(echo 's/2.6/'$VERSION'/g')
  SOURCE=$startdir/pkg/usr/src/linux-$VERSION/ltmodem
  MODULE=$startdir/pkg/lib/modules/$VERSION/kernel/drivers/net
  DAEMON=$startdir/pkg/etc/rc.d
  FILE=$startdir/src/ltmodem-2.6-alk/Makefile.tmp
  sed  -e "$SCRIPT" < $startdir/src/ltmodem-2.6-alk/Makefile > $FILE
  mv $FILE $startdir/src/ltmodem-2.6-alk/Makefile

  cp ltmodem.ko ltserial.ko $MODULE
  cp $startdir/ltmodem $DAEMON
  chmod a+x $DAEMON/ltmodem
}

Here are ltmodem.install and ltmodem (they are not included in ltmodem-8.26-2.tar.bz2)

# arg 1: the new package version
post_install() {

mknod --mode=0604 /dev/ttyLT0 c 62 64

cat << EOF

This package provides the modules for the Lucent Microelectronics LT

To check if your modem is supported, you can use the lspci command or

"http://linmodems.technion.ac.il/packages/scanModem.gz".  The scanModem

In /etc/rc.conf, add ltmodem to the daemons list.

You can set a link to the device.  If you use udev, add
KERNEL="ttyLT0", SYMLINK="modem"
to /etc/udev/rules.d/udev.rules

Note: If pppd quits with an ERROR 1 just after connection, try commenting

# arg 1:  the old package version
post_remove() {
rm /dev/ttyLT0
  /bin/true
}

shift
$op $*
#!/bin/bash

. /etc/rc.conf

    $0 stop
    sleep 1
    $0 start
    ;;
    *)
    echo "Usage $0 {start|stop|restart}"
    ;;
esac

Principal changes:
- I use a install file instead of the README
-the modules are loaded with a daemon
-the modules and sources are intalled in more standard directory

This package is for the 2.6.8.1 kernel.  It will work with the 2.6.7 kernel if the package is rebuilt.

Re: [New package] Drivers for Lucent LT Winmodem

yeah modprobe ppp_generic in daemon file is a good idea
will add this to my package
the mknod in your install file will not have an effect
because the dev tree is built new everytime you restart your pc
(please correct me if i'm wrong)
doesn't udev recognize the new dev when loading the module
the intel drivers work this way
no mknod needed

Re: [New package] Drivers for Lucent LT Winmodem

me again ;-)
add to your install file depmod -a
then the module can be used without a reboot :-)
you can mail me your new package
adress:
t.powa @ >nospam< gmx.de
if everything is alright i add the package to the tur repos

Re: [New package] Drivers for Lucent LT Winmodem

Why write a daemon script to load the modules?  Isn't it better to load them using the MODULES variable in rc.conf?  You could add to you post_install function a note saying that these modules need loading.

Using a daemon to just load modules can become annoying because people could say, "hey! where'd these modules come from?"  Not only that, but it's not doing anything else.  It really does seem like a good candidate for rc.conf.

Re: [New package] Drivers for Lucent LT Winmodem

well see it this way
if you use an other distro the intel drivers install a rc script where it loads the modules that are needed no other user interaction is needed
i would call it user friendly ;-)
i don't think that someone with an internal modem will use a extrenal too so why not loading the modules in the rc script and everything is done?
Well i can add a warning that this will be done and if someone doesn't like it load the modules by hand

EDIT:
my package needs this rc file for starting the hamregistry program
so i added the modules to this file too

with the ltmodem drivers it's a little bit different it loads only modules
i agree there it would make sense to add them only to rc.conf's modules list

Re: [New package] Drivers for Lucent LT Winmodem

changed my package...
added comment to load ppp_generic and modem-driver to modules list
now it's more the arch way
let the user have full control ;-)

i changed your package too (updated to 8.31) please test and give feedback it's now available in staging
pacman -S ltmodem
please change the topic to [in staging]
enjoy
