I think Lonely Wolf is right - you do not need to modify permissions
on /dev/ttyS1. According to the man page, the bcmxcp_usb driver only
supports one UPS, and apparently the port name just has to be some
placeholder value (the man page suggests "auto"). (Not saying that you
should change anything, just that there is no connection.)
