There is a upsdrv_init_nofc() function, but it seems to be brittle in its string matching. > We are running NUT v2.7.1 on CentOS 6.5 with the bestfcom driver.

If so, we can patch it to skip however much white space is present before the "FE". -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
