ok, I took a bit of time to complete my knowledges on this specific topic.
According to what I've found, you should be able to enable the serial
communication using UPS passthrough communication. This should only need
settings on the DIP switches, which should get rid of any driver
modifications.
See the below link, p32, chapter "Serial Pass-Through Mode":
http://lit.powerware.com/ll_download.asp?file=1405E-WebCard-Rel.pdf

Are your DIP switches set to the 1 (on) position? Have you made a reset?

I've made a test on my side, with a 9130 and a connectUPS BD slot (which has
the same features, but not the same form factor. By applying the above
mentioned procedure, I've succeeded in using bcmxcp driver (with a serial to
USB converter). To speed up the driver startup, put "baud_rate=9600" in your
ups.conf section for this UPS.

I will complete the HCL with these information.
thanks for pointing me this feature ;-)

cheers,
Arnaud
