View source for Conectarea unui telefon mobil prin IR

==Introducere==

Acest tutorial prezintă modul de configurare a distribuţiei Slackware Linux 12.0 pentru a permite conectarea la un telefon mobil folosind un adaptor IrDA/USB.

Adaptorul IrDA/USB este de tipul KingSun-959:
<code>Bus 003 Device 002: ID 07d0:4959 Dazzle Kingsun KS-959 Infrared Adapter</code>
<code>
# cat /var/log/dmesg | grep 959
KingSun KS-959 IRDA/USB found at address 3, Vendor: 7d0, Product: 4959
drivers/net/irda/ks959-sir.c: IrDA: Registered KingSun KS-959 device irda0
usbcore: registered new interface driver ks959-sir
</code>

Singurul telefon mobil pe care am testat aceste informaţii este Nokia 5200, deci este posibil ca pentru alte tipuri de telefoane mobile să existe diferenţe în ceea ce priveşte setările descrise în acest tutorial.

Informaţiile au fost testate pe un notebook Fujitsu Amilo Pro v3515 (Slackware-current, kernel 2.6.24.5). Distribuţia a fost instalată cu opţiunea "full". De asemenea, am configurat HAL (Hardware Abstraction Layer) conform [ftp://slackware.cs.utah.edu/pub/slackware/slackware-12.0/CHANGES_AND_HINTS.TXT CHANGES_AND_HINTS.TXT].

Pentru conectivitatea prin infraroșu, am instalat pachetul <tt>irda-utils</tt> de [http://slackbuilds.org/repository/12.0/network/irda-utils/ aici], folosind sursele pachetului de [http://sourceforge.net/project/showfiles.php?group_id=5616 aici], astfel:

<code>
$ cd /home/<user>/Desktop
$ wget -r ftp://ftp.slackbuilds.org/12.0/network/irda-utils
$ mv /home/<user>/Desktop/ftp.slackbuilds.org/12.0/network/irda-utils/*.* /home/<user>/Desktop
$ su
# chmod +x irda-utils.SlackBuild
# ./irda-utils.SlackBuild
# cd /tmp
# installpkg irda-utils-0.9.18-i486-1_SBo.tgz
</code>

==Configurare==

*Încărcarea modulelor de kernel necesare (modificarea fișierului de configurare <tt>/etc/rc.d/rc.molules-<kernel-version>-smp</tt>):
<code>
### IrDA/USB modules
/sbin/modprobe irda-usb
/sbin/modprobe ks959-sir
/sbin/modprobe irtty-sir
/sbin/modprobe ircomm
/sbin/modprobe ircomm_tty
</code>

*Verificarea încărcării modulelor:
<code>
# lsmod
Module                  Size  Used by
ircomm_tty             23944  0
ircomm                 14340  1 ircomm_tty
irtty_sir               8960  0
sir_dev                14596  1 irtty_sir
irda_usb               16772  0
ks959_sir              11648  0
irda                  114360  5 ircomm_tty,ircomm,sir_dev,irda_usb,ks959_sir
crc_ccitt               5760  1 irda
</code>

*Activarea serviciului <tt>IrdA</tt>:
<code>
# cd /etc/rc.d
# chmod 0755 rc.irda
# ./rc.irda start
Starting IrDA: /usr/sbin/irattach
</code>

*Activarea interfeței <tt>irda0</tt>:
<code>
# irattach irda0 -s 1

# ifconfig

irda0     Link encap:IrLAP  HWaddr bf:21:c7:c1

# There are few main models that should make use of the certain drivers.
# These are: 6110, 7110, 6510, 3110, 2110, 6160.

# Set IrDA device name.
irda_string = Nokia 5200

initlength = default

# For infrared connection with phones other than Nokia 6110/6130/6150 use:
connection = irda
# Don't forget to run: 'irattach irda0 -s' or similiar before running gnokii

use_locking = yes

# Baudrate to use on serial port connections.
serial_baudrate = 9200

# Force serial port handshaking mode, useful primarily for "AT" model.
handshake = hardware
