• When a status indicated on the following page is entered, the corresponding bit in the
condition register is set to “1.” The logical AND of the condition register and the lter
becomes the status information.
•
The IF command can be used to set the lter.
•
The IS command is used to output the status information. Status information 1 and 2
are cleared when they are output. Status information 3 and 4 are not cleared when it
is output, and remains at “1” while the event is occurring.
•
When multiple connections are up, lters can be specied for the individual
connection.
Therefore, the status information can be held for each connection.
