hello, and excuse me for posting this again, i just hope to get this solved. i am trying to get the irda (infrared) services to work with my mobile phone, but it does not seemt to work. here is what i have done and how some config files look. i have fedora core 2, kernel 2.6.5-1.358 (selinux=0). dmesg |grep -i tty reports ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A ttyS1 at I/O 0x2f8 (irq = 3) is a NS16550A the second is the infrared port. i used setserial the following way: setserial /dev/ttyS1 port 0x2f8 irq 3 the devices look like: crw-rw---- 1 root root 161, 0 Jun 6 13:11 ircomm0 crw-rw---- 1 root uucp 4, 65 Jun 6 13:11 ttyS1 modules.conf empty modprobe.conf # Note: for use under 2.4, changes must also be made to modules.conf! alias eth0 e100 alias usb-controller usb-uhci alias sound-slot-0 snd-cs46xx alias tty-ldisc-11 irtty alias char-major-161 ircomm-tty # alias char-major-161-* ircomm-tty alias irda-dongle-0 tekram alias irda-dongle-1 esi alias irda-dongle-2 actisys alias irda-dongle-3 actisys alias irda-dongle-4 girbil alias irda-dongle-5 litelink alias irda-dongle-6 airport alias irda-dongle-7 old_belkin alias irda-dongle-8 ep7211_ir alias irda-dongle-9 mcp2120 alias irda-dongle-10 act200l alias irda-dongle-11 ma600 options nsc-ircc dongle_id=0x09 # NSC driver on a IBM Thinkpad laptop alias irda0 nsc-ircc # IRLAN # But currently the IrLAN protocol is no longer maintained # by the Linux/IrDA core team. alias irlan0 irlan install sound-slot-0 /sbin/modprobe --first-time --ignore-install sound-slot-0 && { /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :; } remove sound-slot-0 { /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :; } ; /sbin/modprobe -r --first-time --ignore-remove sound-slot-0 then to have my nokia 6110 mobile phone (with hardware modem) to speak with the computer i have previously been able to do: irattach /dev/ttyS1 -s and then use the /dev/ircomm0 port for communication. however now when i run irattach /dev/ttyS1 -s i get the following in the messages log. Jun 6 13:31:09 computer irattach: irattach: tty: set_disc(11): Bad file descriptor Jun 6 13:31:09 computer irattach: Stopping device /dev/ttyS1 Jun 6 13:31:09 computer irattach: ioctl(SIOCGIFFLAGS): No such device Jun 6 13:31:09 computer irattach: exiting ... i have looked at the descriptions at http://www.tldp.org/HOWTO/Infrared-HOWTO/index.html this has helped before, but this time, nothing. any help would be appreciated. kb __________________________________ Do you Yahoo!?
