Can I break into this thread?  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?
