Here's the dmesg output ......

Yup, there's what I expected. Not setting the baud rate and not writing status registers is unlikely to produce working results. This 9600 must be the default setting being applied.

Here's apcupsd trying to set 2400 baud.Please try the attached patch (against 2.6.22.1). This will allow writing to the baud rate and MCR/LCR registers on non-EPIC adapters. I suspect the previous code was a copy-paste error.
