Response

At the sending side (PC), the transmission is sent within character intervals of Tc (character interval timeout).

At the receiving side (Projector), data able to be received within the character interval of Tc is held, and receiving of a

delimiter is considered “transmission received”.

If a received character interval exceeds Tc or a delimiter is not received within 256 characters, all data already received is

lost, and the mode is reset to receive standby again.

(However, note that a response may not be returned when the internal receive buffer overflows due to reception of a large

amount of data.)
