Problems with irda (irlap, ircomm)

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

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

Sorry for the misspelling!
