4.2.3. Command Processing

The 8010-SIE only responds to commands 0x27 and 0x28. Each of these commands sends a string of
ASCII characters that defines what the message is. Command 0x28H also sends down a 3 ASCII
character location pointer at the beginning of the string of characters. Since the MESSAGE is a
variable length, and there is no byte count associated with the message, the 8010-SIE units use a
timeout to determine when a message is complete. This means that if the MESSAGE portion of the
command is being received and the characters stop coming in for approximately 70 milliseconds the
command will be treated as complete and the MESSAGE will be processed.
The MESSAGE portion of the command is scanned for various character patterns to determine various
status, scenes, etc. The following table shows a list of the information scanned for (in the order of
priority):

The CTL and LVS windows keep track of their positions
on the screen when they are detected. If the blanks

windows the status of the mode will be changed to CTL
