I did get some warnings but compilation and connections have been successful for me. Here's a link to the warnings that I got http://www.geocities.com/olivares14031/slmodemd-2-6-19-1-2895fc6.html I have been hoping for some sort of intervention for continued slmodemd code onto kernels >= 2.6.20, but since the code is proprietary, and not open, it will be difficult. Furthermore, if I recall correctly, smartlink sold out to conexant and they will not support slmodemd since they only work with hsf and hcf based modems served by linuxant. Have you contacted other Arch Linux users about your difficulties? Regards, Antonio ____________________________________________________________________________________ TV dinner still cooling?
