Normally messages can be sent to the projector before processing of earlier messages is complete—
Christie TruLife+ stores messages in a buffer until ready to process. However, if a series of messages
is sent, Christie TruLife+ may not be able to process them as fast as they arrive and the buffer
becomes full.
If this happens, Christie TruLife+ sends the 13h (Xoff) code to instruct the controller (or any devices
preparing to transmit) to cease transmission. At this point, the controller must respond immediately
and send no more than 10 extra characters or they may be lost (such as, Christie TruLife+ can
accommodate the receipt of up to 10 more bytes after it sends 13h (Xoff)). When the buffer is once
again available, Christie TruLife+ sends a 11h (Xon) command to resume transmission.
Xon and Xoff controls apply to both directions of communication. Christie TruLife+ does not send more
than three characters after it has received a 13h (Xoff) code.
