Nut upsuser - Apr 2006 - Powerware 9120 serial connection via USB/serial dongle

I decided to try this to see if it worked better since
Powerware decided to build in some oddball USB
protocol instead of using a HID UPS profile, but it
doesn't seem to work.  The USB/serial dongle is
recognized by Linux and added as /dev/ttyUSB0, owned
by group "dialout", so I had to add the nut user to
the dialout group.  In the compatibility list, the
proper driver for the Powerware is supposedly
upscode2, but it doesn't seem to work:
$ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.0.3
Network UPS Tools - UPScode II UPS driver 0.84 (2.0.3)

Warning: This is an experimental driver.
Some features may not function correctly.

Bad response to UPTP "":
Bad response to UPTP "":
Bad response to UPSN 0:
Missing UPCL after UPCL
Communications with UPS lost: Empty string from UPS
for UPDS!

I thought the USB/serial dongle or serial port might
be bad, so I dual booted into Windows and ran
Powerware's Lanware 5.x software and it found the UPS
properly on COM3.

Any other suggestions? :-P

Hi Ken.

The 9120 is talking bcmxcp. So you should run the bcmxcp driver.

If you have a usb connector on the ups, try the bcmxcp_usb driver.
One problem with the bcmxcp_usb driver is that in the current state it
does not set the ups to 'request only mode', but the serial bcmxcp
driver does it.

Regards
Kjell

Forgot to do a reply-all when I replied to Krell:

Yes, this does work.  I was confused by the
compatibility page that lists both a powerware 9120 
and PW9120.  The 9120 uses the upscode2 driver and the
PW9120 uses the bcmxcp driver.

Why is "request only mode" missing from the bcmxcp_usb
driver?  And what does it do?  No luck finding this
info via Google or the docs..

Thanks again, Kjell :-)
