I believe I mentioned that the UPS has the serial port, the computer thus has USB.
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.
John as always has the deepest insight (why I’m not surprised). Thanks !
