There is a bug in the analog output record that manifests
itself when you have specified a non-zero rate of change
(OROC) and are using hardware that maintains it's output
during a reboot (observed in Allen Bradley). This bug is
at least in 3.11.4 and all 3.12 Beta versions.

When these conditions occur, the output will be driven to
0, then ramp to the value that was readback from the hardware.

In the routine:
static long init_record(pao,pass)
    struct aoRecord     *pao;
    int pass;
{
    struct aodset *pdset;
    long        status=0;
    double      value;

    if (pass==0) return(0);

Need the end of the subroutine is:
        break;
        }
    }
    pao->pval = pao->val;
    return(0);
}

Which should be:
        break;
        }
    }
    pao->oval = pao->pval = pao->val;
    return(0);
}
