[hsflinux] Current HSF driver doesn't work

[Hannes Kuhnert]

Hello,

owning a license I was using an older version of the HSF driver with several 
Linux kernels. But it couldn't be compiled for some newer kernel versions. 
That's why I updated to hsfmodem-7.18.00.07full, which doesn't work with any 
of the Linux kernels installed.

For example for Linux 2.6.12.4, it can be compiles and it is loaded without an 
error. A dialer seems to work as expected at first, but the modem doesn't 
work. Although using the command ATM1, I can't hear it.

For Linux 2.6.15.1, it can be compiled, but loading the modules results in an 
error message. The modem device can't be opened.

Has anyone an idea what could be wrong?

Thanks for help.
