4. Communication Frame
----------------------------------------------------------------------
On the LT/MT/SX/GT series projectors communication is done in a frame
composed of header, data, and checksum.
The frame sent from the controller to the projector is referred to as
a command, and the one sent from the projector to the command as an
reply is referred to as a response.
The response has two types; Acknowledge (hereafter referred to as ACK)
that recognizes a command and Negative Acknowledge (hereafter referred
to as NAK) that fails to recognize a command.
