Sadly not.
Even "null modem" cables were not covered by a standard so you can get different ones. They usually have wires crossed in them (think of cross-over RJ45 cables).
Non "null modem" cables are normally straight through cables.
You need to check the manuals / spec sheets to fine out what you need :)
Re: serial cable question
neither say what cables required, this is the pin outs for the ups though, it does seem to need some crossed

Re: serial cable question
RS232 Pin Assignments (DB9 PC signal set)
Pin 1 Received Line Signal Detector (Data Carrier Detect)
Pin 2 Received Data
Pin 3 Transmit Data
Pin 4 Data Terminal Ready
Pin 5 Signal Ground
Pin 6 Data Set Ready
Pin 7 Request To Send
Pin 8 Clear To Send
Pin 9 Ring Indicator
if thats the pc side, and the diagram above is the UPS then it seems to be a straight through cable after all, not a null modem. so a straight forward extension cable should do the trick ?
