Example of Status Read Command: “CR0” [CR]

3. When it takes more than one second to receive one command, it does not operate.

The information of buffer is cleared when it takes more than one second to receive carriage return

(0x0D) after the projector receives the first data “C”.

4. For Command pipelining, wait for the interval of 100ms after receiving a response.
