I've found it best to compile from source for the lucent winmodem. I never got the binary to run any machine.
I have a IBM T20 laptop running SuSE 8.1. I now like to get the internal modem up and running but struggle doing this. When I try to install the binary for the modem I get a "Failed dependencies" error - see below.
I grabbed the binary from http://www.heby.de/ltmodem (following the link to the SuSE binaries).
