Can you try the USB port? The 2U models switched from the proprietary  
Tripp-Lite signaling (use the tripplite_usb driver) to HID PDC (use  
the usbhid-ups driver) at some point, but I don't know how well the  
usbhid-ups driver has been tested on *BSD.

If that doesn't work, you can try echoing an identification command  
to the serial port, and see what it returns (untested):

$ stty -f /dev/cuad0 raw
$ echo -ne ':\000\377\015' > /dev/cuad0
$ hd < /dev/cuad0

Let me know if you get any errors with this, or if it plain doesn't  
work - I don't have a serial UPS to verify this sequence of commands.

There was talk of consolidating the USB and serial Tripp Lite  
drivers, and if/when that happens, there's a better chance that we  
can support odd models.
