I think that, on
some models at least, APC UPSes just use DSR and CTS
instead of transmitting data. The place I used to work at made their own
all the time.
I did investigate the pin-out after I bought mine; they seem to use
all pins and I seem to remember that a couple are looped back?
Anyway, they sure were nonstandard. They have different kinds of
cables, though.
