I have a wagon load of heyu related scripts I run here, controlling outside lighting etc. Under FC2, they run just fine. But booted to FC6, all I can get out of tracing things is that it cannot open /dev/ttyS1, so the whole thing falls over. selinux is set permissive, and an ls -l of /dev/ttyS* show this: crw-rw---- 1 root uucp 4, 64 Nov 9 16:35 /dev/ttyS0 crw------- 1 root root 4, 65 Nov 9 16:35 /dev/ttyS1 crw------- 1 root root 4, 66 Nov 9 16:35 /dev/ttyS2 crw------- 1 root root 4, 67 Nov 9 16:35 /dev/ttyS3 And the heyu stuff is running as root. What else can I check & possibly adjust? >Thanks for the help. > >stan -- Cheers, Gene
