Nut upsuser - Sep 2008 - Tripplite SMX1500XLRT2U through serial

Hello list-

Anyone with Tripplite SMX1500XLRT2U
(http://www.tripplite.com/EN/products/model.cfm?txtModelID=2687)
successfully integrated with NUT through serial port? I'm trying to
connect to SMX1500XLRT2U using serial cable shipped with UPS under
FreeBSD 6.3-STABLE and NUT 2.2.2 installed from ports. Unfortunately,
it looks like it couldn't be recognized.

%dmesg | grep sio
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on
acpi0
sio0: type 16550A
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1: port may not be enabled

ups.conf:

[tripplite]
driver = tripplite
port = /dev/cuad0

%/usr/local/libexec/nut/tripplite -a tripplite -DDDDD
Network UPS Tools - Tripp-Lite SmartUPS driver 0.8 (2.2.2)
debug level is '5'

Failed to find UPS - giving up...

I played with different NUT drivers (including genericups) to no available.

Any hints would be greatly appreciated!

Thank you.

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.
