This come from the baudhunting function in the driver.
If you set the baud_rate in the ups.conf to 9600 You don't get this
errors.

Ex:
[pw5115]
    driver = bcmxcp
    port = /dev/ttyS0
    shutdown_delay = 90
    baud_rate = 9600
    desc = "COM ups"

It's done this way because if you don't know the baudrate it test
from 1200 to 19200 baud and connect on the right speed.

The first error is 1200 next 2400 then 4800 and then you have
a successful connect on 9600.

Kjell
