I saw those "LSR safety check engaged" messages once, I think with 
non-MultiTech hardware, though.  It had to do with IRQ problems or a 
loose card.  I can't remember exactly anymore.

Well, it doesn't appear to be anything that HylaFAX is doing

I'm not a big fan of running faxgetty on symlinks, if it can be 
avoided.  Why are you?
