At the very least most cheap USB to serial will not work. They do not
implement the CTS/DTR sets of control lines, which is used for many of
the UPS's simple signaling. A dongle that explicitly implements those
signal lines should work. (I've had trouble with amateur radio remote
control with these half assed cheap adapters.)
