Flow control

Normally messages can be sent to the projector before processing of earlier messages is complete—
Mirage SST stores messages in a buffer until ready to process. However, if a series of messages is
sent, Mirage SST may not be able to process them as fast as they arrive and the buffer becomes full.
If this happens, Mirage SST 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, Mirage SST can
accommodate the receipt of up to 10 more bytes after it sends 13h (Xoff)). When the buffer is once
again available, Mirage SST sends a 11h (Xon) command to resume transmission.
Xon and Xoff controls apply to both directions of communication. Mirage SST does not send more than
three characters after it has received a 13h (Xoff) code.
