yes, I know this page (google rules :-). Anyways, I thought that FIR and SIR are two different infrared protocols and devices which work on one don't work on the other. Now I understand what it means. So, I play with SIR now (I need only 9600bps dialout, so speed really doesn't matter to me yet). > So, ok, Fast Infrared (FIR) maybe doesn't work, but you should be able to get > normal infrared (SIR) working. > > I don't have your machine, but maybe I can give you some advice ok, I reconfigured irda-common, selected serial, /dev/ttyS1 and for dongle none. Now the messages from kernel are: Jun 8 11:49:10 jurajbug kernel: IrDA: Registered device irda0 Jun 8 11:49:11 jurajbug irattach: executing: 'echo 1 > /proc/sys/net/irda/discovery' Jun 8 11:49:11 jurajbug irattach: Starting device irda0 Jun 8 11:49:11 jurajbug irattach: executing: 'echo jurajbug > /proc/sys/net/irda/devname' Jun 8 11:49:11 jurajbug kernel: irtty_net_open() Jun 8 11:49:11 jurajbug kernel: irlap_change_speed(), setting speed to 9600 Anyways, irdadump says nothing :(. > Check the that the IR port in the BIOS is set to SIR, and doesn't have > FIR enabled. there's no such setting in my bios, I can only set IRQ, I/O Port and DMA channel under Infrared setting.

That's all I can get from irdadump, sometimes after initialization. (the phone's infraport was turned off at this time, I turned it on later and irdadump wrote nothing about it).
