Flow control

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