Hi, the last kernel slusb worked with was 2.6.18.2-34-default, Suse 10.2 with slmodem-2.9.10. I compiled the latest version on SuSe 11.4. But slusb wasn't compiled, only slamr. I tediously searched the site of linmodem, but didn't find an answer whats to do. SuSe 11.4 comes with kernel 2.6.37 The Modem in question is a Fujitsu Siemens USB-Modem. As I said, it works fine with older kernels and older Versions of slmodem. If there is some programming to be done, please let me know. Though I am much better in Perl than in C/C++, if necessary I would try to solve the problems. Could somebody give me a short briefing? Greetings Bernd
