Hi all,
I have just discovered something that seems to me to be a bug in the
mbbi record support routines. When status-values are defined but the
current raw value doesn't fit any of them, the value will become 65535
and the UDF bit will be set. In the alarm routine UDF causes an invalid
severity error which can not be overwritten by something else. This
leads to the situation that the setting of the UNSV field is without any
effect.
I propose to delete all existing manipulations of UDF in process() and
insert only one "..->udf = FALSE" when the raw value is successfully
read. This is the place after "if (status == 0)". This works fine for
me. Any comments?
