yes, but is it 'basic serial UPS' or is it 'enhanced serial UPS' ?    the
former do NOT use the rx/tx data of the serial port at all, they ONLY use
the serial port control  signals, and they probably will NOT work with a
USB port because they require very specific behavior from those signals at
power up and reboot times.

the latter DO use the serial data, and may work with USB serial.
