From: DaveC on 18 Apr 2010 11:41 I'm installing the UPS (battery back-up) monitoring program apcupsd. After basic configuration, I can't get apcupsd to run. It stops immediately, reporting: Cannot open UPS port tty.PL2303-000053FD: No such file or directory yet when I list all devices it shows up exactly as "tty.PL2303-000053FD". If another process is using this port, will this generate this error? How do I determine if a port is being used by a process? Which process? Thanks.

Open a terminal window (terminal is in utilities which is in applications). Then you can use the standard UNIX commands, lsof (list open files), ps (display processes, lots of options) and so on.

Which process? You're in luck. I've a decent amount of experience with apcupsd - great utility! How are you trying to "run" it? In normal operation, apcupsd runs automatically at startup as a background daemon. You don't have much, if any, direct interaction with it. To see if the daemon is already running, issue this command: /sbin/apcaccess If it's running you will see a screen dump showing lots of juicy information about your UPS - something like this: APC : 001,037,0997 DATE : 2010-04-18 11:22:19 -0500 HOSTNAME : server.domain.net VERSION : 3.14.8 (16 January 2010) darwin UPSNAME : server CABLE : USB Cable MODEL : Back-UPS ES 725 UPSMODE : Stand Alone STARTTIME: 2010-03-18 16:13:44 -0500 STATUS : ONLINE LINEV : 122.0 Volts LOADPCT : 33.0 Percent Load Capacity BCHARGE : 100.0 Percent TIMELEFT : 6.0 Minutes MBATTCHG : 5 Percent MINTIMEL : 3 Minutes MAXTIME : 0 Seconds SENSE : High LOTRANS : 088.0 Volts HITRANS : 138.0 Volts ALARMDEL : Always BATTV : 13.5 Volts LASTXFER : Automatic or explicit self test NUMXFERS : 5 XONBATT : 2010-04-06 04:51:24 -0500 TONBATT : 0 seconds CUMONBATT: 11 seconds XOFFBATT : 2010-04-06 04:51:32 -0500 LASTSTEST: 2010-04-06 04:51:24 -0500 STATFLAG : 0x07000008 Status Flag MANDATE : 2002-11-29 SERIALNO : QB0248162487 BATTDATE : 2002-11-29 NOMINV : 120 Volts NOMBATTV : 12.0 Volts FIRMWARE : 802.n2.D USB FW:n2 APCMODEL : Back-UPS ES 725 END APC : 2010-04-18 11:22:54 -0500 -- Send responses to the relevant news group rather than email to me.

Good point. For most people, the built-in Mac OS X UPS support will do. My Mac Pro is the only machine connected to one of my UPSs; I just use the built-in Mac OS X UPS support for it. I also have multiple Mac minis and a Mac SE/30 in a server closet, all of which are connected to the same UPS device. I use apcupsd there because I want to shut them all down when needed. -- Send responses to the relevant news group rather than email to me.
