When 40 or more key codes exist, they are divided in units of 40 maximum and the rest to
be sent.
• Status with a group of consecutive transmit data groups is 41H.
• Status without a group of consecutive transmit data is 40H.
After sending [Header - NUL], a response is received from host and next processing
corresponding to the response is executed.
• In case of “Status (with continuous block): hexadecimal number = 41H / decimal number = 65”
