Hi
I am a beginner to Linux. I am unable to use my Motorola SM56 modem in Fedora Core-1. While searching on net… I got an rpm from
motorola softmodem site....
motorola.com/softmodem/public_download/Linux/sm56-06.05.00-1.rh9.i386.rpm...

The installation output of the above rpm was …

**************************************************************************************************** ***********************************

Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. The module may be trying to access
GPLONLY symbols but the problem is more likely to be a coding or
user error. Contact the module supplier for assistance, only they
can help you.


After this rpm installation, KPPP looks for the modem and stops with an error … unable to open the modem.

Could you help me ..Plzzz…

Thanks

The tty_(un)register_driver and (un)register_chrdev functions are essential to many modules so they are definitely present. The _R536a8785 and similar strings indicate that the module expects versioned symbols and it is most likely here where the problem lies. There are two possibilities: either your kernel has been compiled without versioned symbols or the function's definitions have changed making them incompatible. The way to find out is to look at the contents of /proc/ksyms which lists the symbols exported to kernel space. If they all have a _R... extension on the end then you have a versioned kernel and the module is incompatible. If they are missing then the kernel isn't using versioned symbols. In the latter case it may be possible to create compatibility by making a module which exports the necessary symbols under the versioned names and simply calls the non-versioned counterparts in the kernel. It is however my suspicion that the kernel is versioned and that the module is simply incompatible with your kernel. In this case running the RH 9 kernel (which I assume from this evidence differs from a FC 1 kernel) instead of your present kernel may work.

peace!

Did you have any luck? please tell us.
