This is a load of, uh, horsefeathers! They have two cables: one for simple "grunt! power gone, tarzan says shutdown soon" which uses the '232 status lines and one for advanced "You have 12.5 minutes at the current load of 677VA before I have to shutdown, sir". The advanced cable is meant for the SmartUPS(tm) hardware in conjunction with the PowerChute Plus(tm) software. It is rather cool to use. I haven't seen anything for FreeBSD, but their SCO Unix(tm) version worked fine under Linux's SCO emulation when we tired of SCO support. When we asked APC, we were told we could have the protocol if we signed a NDA, we told them we wanted to do something we could release publicly so an NDA was out of the question. We never got any protocol from them, so anything we work on isn't tainted. THe protocol isn't much different, in concept, from the Best equipment once you get the cable figured-out. I liked Best's products, but APC became more cost-effective for us. I got a cable for $5 at a local Tandy surplus store with the Novell/IPX version of PS+. We found some protocol by watching with a serial snooper and experimenting w/cu. Just go down the alphabet typing everything but 'ZZZ' and you will be fine. If you can't find a cable to ohm-out yourself, send some email and I can take one of ours loose and do it. We've done it before, but it must be in an OLD home directory somewhere because it's not new. I did find the stuff for our AST Manhattan (really a deltec in sheeps clothing, but that won't help you, sorry... There have been several folks that have made this work in the Linux crowd, so you might try looking through their archives as well.
