Yes, you are right. But sometimes occurs the need to reboot the computer from the UPS itself - for example when the computer does not response - you cannot login and the attached UPS restarting is the only way. > Note that if you have the choice between monitoring the UPS through SNMP > and serial port, the latter is the better option.

There is still not only gracefull reboot, but even the gracefull poweroff - both are missing in the driver. Thank you for your help.
