[Nut-upsuser] SU2200RTXLCD2U and protocol 4006

[Larry Fahnoe]

I don't have the Tripp-Lite model that you have, however the NUT HCL
http://networkupstools.org/stable-hcl.html suggests that the SU2200RTXLCD2U
ought to work via USB.  Tripp-Lite sometimes uses proprietary serial
cables, so you may need to hunt down a pinout for the serial cable this
unit requires.  If you need to use a serial connection, I'd start by
looking at how their PowerAlert software connects to the UPS and then go
from there to see if you can provide a similar connection to your NUT
master.
