[Function] (1) It transmits the designated NV graphics key code list
With the key code
Hex Decimal Data number
Header 37H 55 1 byte
Identification 72H 114 1 byte
Status 40H or 41H 64 or 65 1 byte
Data 30H ~ 39H 48~57 2~80 bytes
N U L 00H 0 1 byte
Without the key code
Hex Decimal Data number
Header 37H 55 1 byte
Identification 72H 114 1 byte
Status 40H 64 1 byte
N U L 00H 0 1 byte
(2) It divides and transmits the key code with the upper limits of 40 when over 40 key codes exist.
The status is 41H if the continuous transmission data group exists.
The status is 40H if the continuous transmission data group does not exist.
(3) It receives a response from the host after transmission from the header to NUL and executes
the following process corresponding to the response.
Status (with continuous block): Hex=41H/Decimal =65
Response Processing items
ASCII Decimal
ACK 6 Transmits the next data group
NAK 21 Re-transmits the prior data group
CAN 24 Stops the process
Status (final block): Hex=40H/Decimal =64
Response Processing items
ASCII Decimal
ACK 6 Finishes the process
NAK 21 Re-transmits the prior data group
CAN 24 Stops the process
