    Winmodem on Linux


    I have Redhat 8 and a zoom 56k modem. It has a Lucent DSP chipset, and I downlaoded the rpm that is supposed to make it work from
    http://www.heby.de/ and it does, until i try to load the kernel module lt_serial.o
    It then gives me 13 'undefined character' errors and doesn't load the module.

    I sent the error messages to discuss@linmodems.org

    Anyone here know what the matter is.

    Undefined character?! I have never heard of such an error message before. Can you post the exact output of when you try and load the driver?

    This is the email i sent to discuss@linmodems.org:
    (and sorry, in the previous post i said undefined, i meant unresolved
    ----------------------------------
    Dear linmodems,

    When I run the utility checkout, everything but lt_serial loads. When checkout does insmod lt_serial.o (with the full file paths too) I get this error message:

    /lib/modules/2.4.18-14/ltmodem/lt_serial.o: unresolved symbol add_wait_queue_R11dfb1e5
    /lib/modules/2.4.18-14/ltmodem/lt_serial.o: unresolved symbol remove_wait_queue_Rb3afbf37

    /lib/modules/2.4.18-14/ltmodem/lt_serial.o: insmod /lib/modules/2.4.18-14/ltmodem/lt_serial.o failed

    In checkout, I continued on with the diagnostic section after lt_serial failed to load. Unloading unnecessary modules did not help. As I said before, this is the only problem I'm having with the rpm so far. I attached LTinstall.txt as recommended in your docs.
    -----------------------------------------------------------------

    And the extra R38cf3588 stuff at the end of the error lines was certain ascii symbols on linux, but when i transferred the error message via floppy to windows, windows replaced the symbols with that junk[/i]

    Unresolved symbol says a lot more...
    It seems to me that that module requires other modules to load. Have you tried modprobe lt_serial instead (providing that you've made a make install from source and run depmod -a)?

    I installed from an rpm (from www.heby.de) and yes, I did try depmod -a

    But have you tried running "modprobe lt_serial" instead of "insmod lt_serial.o"?

    cant remember, ill have to try it again.

    While im on this subject, is anyone familiar with discuss@linmodems.org, the way they are supposed to respond to you? Do they email you back, or is your problem answered on linmodems.org in the mail archives section?

    Are you sure it's not a mailing list?
