N-File Description

N41

For Single Mode Only

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 adapter 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 adapter is not mapped to the scanner.

• The value of N42:3 is set to a non-zero value.

adapter is connected.
