APCUPSD on Alix2d13

[giacomo]

Hi All,

I've installed APCUPSD on pfSense 2.2.6 on Alix2d13.
It give me this error:

apcupsd[43720]: apcupsd FATAL ERROR in smartsetup.c at line 155 PANIC! Cannot communicate with UPS via serial port. Please make sure the port specified on the DEVICE directive is correct, and that your cable specification on the UPSCABLE directive is correct.

Could be that the problem is that the serial port is already used by pfSense console?
If this is the problem, is it possible to disable the console?

Thank you!
