Figure 9.1 Control-T Frame Format
When using a Function, a display address must be included, even if it
is a broadcast address of 255.
Using a Priority message will clear all concurrently running messages
and display the message number just sent. This will supersede any
message that has been added to the queue regardless of priority levels
assigned to them.
Add/Remove messages allows for the ability of up to 64 concurrently
running messages to be displayed. Messages are added to the queue
and will be displayed for the length of time based on the message
pause setting (1-5 seconds). Messages can have three different priority
levels assigned to them; Low, Medium, and High. Messages with the
highest priority level in the queue will be displayed until they are
cleared. When all messages are removed or cleared, the Background
Message (message # 4095) is displayed.
