Creating a Message That Requires Acknowledgement

To ensure that important messages are displayed and acknowledged by an
operator, you can configure a message to require acknowledgement. This
message flashes when displayed on the TD 200. The operator must press the
ENTER key on the TD 200 to acknowledge the message.
When the message is acknowledged, the following things happen:
The message stops flashing.
The acknowledge-notification bit is set in the CPU.
The message-enabled bit for this message is reset in the CPU.
To force acknowledgement of a message, embed a format word in the message.
The format word tells the TD 200 how to display the message. The format word
uses two contiguous characters within your message. Since there is no data
associated with this format word, the format word can be placed anywhere in your
message (not just at the end). The format characters appear as blank spaces on
the TD 200 display.
