Looking at the sources, it is quite obvious where this error occurs (in
upsdrv_updateinfo). Sending a command to the UPS apparently is not a
problem, but the '-1' indicates that the UPS is not responding at all
(most likely, ser_get_buf_len times out). I agree with Charles' remark to
checkout the cable.
