Nut upsdev - Jul 2009 - Liebert Power Sure PSPXT 450 (SERIAL)

Hi!

My Liebert Power Sure PSPXT 450 with standard driver doesn't works, so
I've
done this modification and now it's works.

# diff liebert_MY.c liebert.c
178
< ser_set_speed(upsfd, device_path, B9600);
---


That is, I've only setup the port's speed.

Can you update SVN code?
Thanks

Bye

If the comments in the code are correct, it should not matter what the
baud rate was set to (the TX and RX pins are apparently connected
together when on battery).

Do you know what speed your serial port was using before that fix?

Since this driver is marked "experimental", I suppose we can add that
without worrying too much.

Any objections from the other developers?
