Hello! The command "cat /dev/isdninfo" should echo status information about the isdn-devices, but wiht Redhat 6.2 it doesn't. ISDN works perfectly on my system and when I use isdnlog with the -v4 option, the informations that "cat /dev/isdninfo" should report are shown in the log file. As a result some tools that depend on that function don't work. I've triede several things to fix this, but nothing helps - compiled a new kernel to ensure isdn module support - compiled and installed isdn4k-utils after deleting /dev/isdn* - asked in the german isdn4linux Newsgroups for help, but nobody (even S.u.S.E. staff) could help me to fix the problem. BTW: Why don't you start isdnlog in /etc/rc.d/init.d/isdn with the -D option? ps -ax|grep S80isdn shows, that the script doesn't end until I changed this.
Update the new kernel on ftp.redhat.com will fix this problem.
