7.8 Command Responses
The converter does not, in general, produce output unless in response to an
operator command. The only exception to this is the auto log off warning message
and the log off message (when log off is initiated automatically).
The auto log off warning message is as follows:
WARNING: Auto log off imminent!
When a syntactically correct command has been issued to the converter,
acceptance is indicated by the Command Executed output as follows:
EXECUTED
An invalid command will not be acted upon. The converter indicates command
rejection by issuing one of the following responses. Note that only the first error
detected in a command will be indicated.
