Marvin, Jacques, Finally It worked! The ltmodem became linmodem. The initial approach didn't work because the kernel-headers from my debian cd set wasn't right. That file modversions.h was really missing. I downloaded the kernel-headers from debian repos, as you said Marvin and then I tried ./build_module. Your scripts simply guided me through the process. They are wonderfull! Then, I didn't have wvdial installed so I configured my ISP settings with pppconfig. And... I'm sending you this e-mail with my debian box and LT modem. Thank you very much for your help, you've been very kind.
