I have recognized that mISDN is not working in this mode (if I am using 32/32 mode everything is fine). Logs tell me that ioctl calls fail. It seems that they are not compatible running in mix mode (I did not test pur 64 bit mode). I have used mISDN-drivers (v2) from kernel (2.6.28.10, 2.6.30 and 2.6.31.2) and tried to start mISDNuser tools: A socket connection is established but every socket connection through ioctl is going to fail. "Oct 14 14:51:20 localhost kernel: ioctl32(misdnportinfo:8098): Unknown cmd fd(3) cmd(80044943){t:'I';sz:4} arg(ffa7b5b4) on socket:[107121]" At the isdn4linux mailing list I have read some months ago that it is also not working with a pur 64 bit system. Is anybody able and willing to work on this problem? Thanks for help Alex
