Hi, /dev/cuaa0 is the com port in this case the equivalent of com1 and /dev/cuaa1 is com2. It shouldn't lock you box like that. Did you install a pre-compiled package or did you compile it using the ports? Check the permissions. ls -l /dev/cuaa* On my 4.1-STABLE box, crw-rw---- 1 uucp dialer 28, 128 Jul 31 22:57 /dev/cuaa0 crw-rw---- 1 uucp dialer 28, 129 Jul 31 22:57 /dev/cuaa1 This means that nobody else have access unless you're user name is uucp or you belong to the dialer group. I'm not sure what this looks like on a 3.4 box. Make sure on which com port the ups is connected and set the permissions so that other have access to it as well. chmod o+rw /dev/cuaa0 if it is on com1 or chmod o+rw /dev/cuaa1 if it is connected to com2. Also change the device entry in the config file to the correct com port. After all this it might still lock your box. Execute the sync command before so that all the buffers are flushed to disk or boot into single user mode and run it from there after mounting the relevant file systems. "/dev/cuaa0" refers to com1 and /dev/cuaa1 On Thu, Aug 03, 2000 at 11:15:09AM -0600, Joe.Warner@smed.com wrote: > > > Hi, I recently hooked up a UPS (APC Smart-UPS) to my FreeBSD (3.4) machine > and installed upsd-2.0 from the ports collection on the CD ROM set.
