[Nut-upsuser] Cannot connect to a GPSER on serial, USB returning wrong data

[Dan Craciun]

Hi,

I'm using Nut 2.7.2 with riello_ser and riello_usb 0.3 (upgraded from
0.2). Raspbian on Raspberry PI model 2015.

The drivers work on SENTR models.

But on several GPSER the behaviour is erratic:
- usually, the serial driver cannot connect with the UPS. But, when left
on for several days, I found that it suddenly connected on one machine...
- the usb driver connects immediately, but failes to recognize the UPS
model and the readings are wrong. The GPSER models we have are single
phase, the drive sees them as 3-phase. The output of upsc is below.
You'll notice a lot of 52432 values.

How can I debug this?
