The latter won't provide any more useful output, since the powermust
driver doesn't use the upsdebug/upsdebugx commands at all (unfortunately).
Neil might want to do a serial PnP probe, to see if anything is attached
to the port and recognized (serial_probe). This is a long shot though,
since even many recent serial UPSes don't support serial PnP and will
remain silent until activated by a driver.
