He already did (see the remainder of the message). It looks like the
megatec driver is unable to correctly parse the response to the Q1
command, since it is reporting neither the battery voltage, nor the
frequency (although both are in the return message):

> Asking for UPS status [Q1]...
> Q1 => OK [(119.8 119.8 121.6 NNN 60.2 13.6 N/.A 00001001]

The sscanf() function won't deal with this properly, since the return
value contains non-numeric fields, where it expects floats. In order to
correct this, you'd need to break up the reply fields on the whitespace,
so that errors in the parsing of one field don't propagate into following
fields (similar to what is done for the temperature now).

Best regards, Arjen
