    Hello,
    I got a problem with my irda stuff.
    Version: "Linux version 2.4.2-pre2 (root@gozfand.ze) (gcc version 2.96
    20000731 (Red Hat Linux 7.0)) #1 SMP Sat Feb 10 02:26:51 CET 2001"

    I try to dial to the Internet via a cellphone/irda (Nokia 8850) Dongle =
    Tekram IrMate 210B dongle

    It works fine on the v2.2 kernel, but it dosen't work so nice on v2.4
    (2.4.0 -> 2.4.2pre2 and all ac's)

    I got irda-utils-0.9.13.tar.gz and irda-utils-0.9.13-5.i386.rpm (both works
    exactly the same) and pppd version 2.4.0b2-2.
    Started the ir with this command: irattach /dev/ttyS0 -d tekram

            Feb 10 17:46:01 gozfand kernel: IrLAP, no activity on link!
            Feb 10 17:46:10 gozfand chat[2608]: warning: read() on stdin returned 0
            Feb 10 17:46:10 gozfand chat[2608]: send (+++)
            Feb 10 17:46:11 gozfand chat[2608]: -- write failed: Input/output error
            Feb 10 17:46:11 gozfand chat[2608]: Failed
            Feb 10 17:46:11 gozfand chat[2608]: Can't restore terminal parameters:
    Input/output error
            Feb 10 17:46:11 gozfand pppd[2606]: Connect script failed

    I get that problem. After like 20 tryes, i can get the link up, for a
    shortwhile.. then the message "IrLAP, no activity on link!" appears. And
    kills the link.

    I have this under irda support in the menuconfig:
            <M> IrDA subsystem support
            <M> IrCOMM protocol
            [*] Ultra (connectionless) protocol
            [*] IrDA protocol options
            [*] Cache last LSAP
            [*] Fast RRs
            <M> IrTTY (uses Linux serial driver)
            <M> IrPORT (IrDA serial driver)
            [*] Serial dongle support
            <M> Tekram IrMate 210B dongle
    And this is from "lsmod":
            ircomm-tty 32144 0
            ircomm 13904 0 [ircomm-tty]
            tekram 2192 1 (autoclean)
            irtty 7728 2 (autoclean)
            irda 157904 1 (autoclean) [ircomm-tty ircomm tekram
    irtty]

    I have tryed it on a other computer, with rh7 2.4, and it was the same
    there.

    Sorry for the misspelling!

    Thanks,
    Fredrik Falk
