I have discovered that if you build a custom cable you can use the
genericups driver (tha cable supplied with the UPS does not work)...
I have build a "normal" RS232 DTE-DCE cable (I have connected pin 1 with
pin 1, pin 2 with pin 2, and so on... using two DB-9 connectors) AND I
have used 3 pull-up resistors (I have used 4.7 KOhm) between pin 7 and
pin 9 (RTS to RING), pin 7 and pin 8 (RTS to CTS) and between pin 4 and
pin 1 (DTR to DCD)...
With this cable the following configuration works...

[myups]
driver=genericups
port=/dev/ttyS0
desc="My UPS"
upstype=0
mfr="Riello Dialog Plus"
model="Dialog Plus 2200VA"
sdtime=20
OL=RNG
LB=-CTS
SD=ST
CP=DTR+RTS

there is another signal (DCD) that comunicate the failure of the UPS and
the DSR that go to zero when the cable is not connected...

someone can add a new upstype to the next releas of nut?
