Information
When logging synchronous is enabled, unsolicited messages appear between software prompts and
outputs. Only the messages with a severity at or below the set level are sent to the console.
If the message queue limit is reached on a terminal line and messages are discarded, a system message
appears on that terminal line. Messages may continue to appear on other terminal lines.
