Yes, the supplied RS232 cable only has three connected pins. Without
setting 'cablepower=none', the driver didn't detect the UPS.

I tried 'cypress', 'krauler', 'ippon' and 'phoenix'. The driver only
detects the UPS with 'phoenix'.

Using ' -DDDDD -a myups -x subdriver=ippon' I see there is *some*
communication - the UPS responds to Q1 command, but then it all fails
with this:

Hope this helps.

There are some timeout using 'phoenix' too, but generally it works and I
can use 'upsc myups' to get the data...
