Status messages
This area contains status messages that are determined by status bits that are resident in the IOP. The
messages are in pairs as defined in the following table. The first message of each pair is the message that
is displayed if the status bit is on. The status bits can be considered to be independent of one another, so
the message pairs can appear in any combination.
