Flow control
Normally messages can be sent to the projector before processing of earlier messages is complete—
Boxer 4K stores messages in a buffer until ready to process. However, if a series of messages is sent,
Boxer 4K may not be able to process them as fast as they arrive and the buffer becomes full.
If this happens, Boxer 4K 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, Boxer 4K can accommodate
the receipt of up to 10 more bytes after it sends 13h (Xoff)). When the buffer is once again available,
Boxer 4K sends a 11h (Xon) command to resume transmission.
Xon and Xoff controls apply to both directions of communication. Boxer 4K does not send more than
three characters after it has received a 13h (Xoff) code.
