Dotaz: Jak zjistit, kam mam pripojit (irattach) irda v notebooku?

[Zdeněk Hurák]

Potrebuji snad jen jednoduchou radu/nasmerovani, jak poznam, kam pripojit (irattach) irda v notebooku? Ani po dlouhem surfovani a cteni irda howto si nevim rady. Hodne z tech rad se tyka externich zarizeni (aspon tak si prekladam to slovicko dongle), ale ja mam infra uz na desce.

Mam laptotp HP nx5000. Co je vevnitr za infra hw, to se mi nijak zjistovat nedari (lspci nic takoveho neukaze). Takze mam zkompilovan system (Gentoo 2.6.16) s nastavenim:

CONFIG_IRDA=m # CONFIG_IRLAN is not set CONFIG_IRNET=m CONFIG_IRCOMM=m # CONFIG_IRDA_ULTRA is not set CONFIG_IRDA_CACHE_LAST_LSAP=y CONFIG_IRDA_FAST_RR=y # CONFIG_IRDA_DEBUG is not set # SIR device drivers CONFIG_IRTTY_SIR=m # Old SIR device drivers # CONFIG_IRPORT_SIR is not set # FIR device drivers # CONFIG_USB_IRDA is not set # CONFIG_SIGMATEL_FIR is not set # CONFIG_NSC_FIR is not set # CONFIG_WINBOND_FIR is not set # CONFIG_TOSHIBA_FIR is not set CONFIG_SMC_IRCC_FIR=m # CONFIG_ALI_FIR is not set # CONFIG_VLSI_FIR is not set # CONFIG_VIA_FIR is not set

Natazeny mam moduly:

ircomm_tty 18440 0 ircomm 9732 1 ircomm_tty irtty_sir 4864 0 sir_dev 12716 1 irtty_sir irda 96440 3 ircomm_tty,ircomm,sir_dev

Nainstalovano mam irda-utils avsak po spusteni irda dostanu:

note-zhurak linux # /etc/init.d/irda start * Caching service dependencies ... [ ok ] * Starting IrDA ... Failed to open device /dev/ttyS0: Too many levels of symbolic links

V konfiguracnim soubouru pro irda mam totiz

IRDA=yes IRDADEV=/dev/ttyS0 #Set (optional) Dongle name here #DONGLE=actisys+ DISCOVERY=yes

a IRDADEV je asi spatne. Zkousel jsem prejmenovavat bez rozmyslu na /dev/ttyS1 a /dev/ttyS2 ale bez vysledku. Nekde doporucovany prikaz

note-zhurak hurak # cat /proc/net/irda/discovery IrLMP: Discovery log:

mi taky nepomaha, protoze nic nevrati.

V dmesg mam hlasku:

serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A serial8250: ttyS2 at I/O 0x3e8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A irda: Unknown parameter `irtty'

Budu rad za jakekoliv nasmerovani. Procitani webovych stranek jednotlivych lidi, kteri se to na jejich pocitaci povedlo, je vazne velmi vysilujici, kdyz ma kazdy trebas i jen trochu jine zelezo.

Dekuji.

Jak zjistit, kam pripojit irattach neporadim, sam jsem to zjistil nahodou. Na svem starem notebooku LEO, Slackware 10.2, kernel 2.4.31, spoustim IrDA takto:

insmod serial
setserial /dev/ttyS0 -v port 0x3f8 irq 10
insmod irda
insmod irtty
irattach /dev/ttyS0 -s


po vlozeni modulu serial pise dmesg:

ttyS00 at 0x03f8 (irq=4) is a 16550A
ttyS03 at 0x02e8 (irq=3) is a 16550A


irq pro /dev/ttyS0 ma byt ale 10 nikoliv 4, coz jsem zjistil, kdyz jsem spustil Windows 98, kde IrDA fungovalo bez problemu.
