This N-file lets you read and write control I/O messages. You can write control I/O
messages only when all of the following conditions are true:
• The module is not receiving I/O from a scanner. For example, there is no
scanner on the network, the scanner is in idle (program) mode, the scanner
is faulted, or the module is not mapped to the scanner.
• The value of N42:3 is set to a non-zero value.
