[Description]

Transmits the key code list for defined NV graphics. The transmission data groups are as indicated in the following table.

Key code data groups	Hex	Decimal	Number of data
(1) Header	57h	87	1 byte
(2) Identifier	72h	114	1 byte
(3) Display number	30h - 39h	48 – 57	0–2 bytes
(4) Separator	1Fh	31	1 byte
(5) Identifier status	40h or 41h	64 or 65	1 byte
(6) Data	20h – 7Eh	32 – 126	0–80 bytes
(7) NULL	00h	0	1 byte

- [(5) Identifier status] indicates the presence of a following transmission data group.
- - If there is unsent data, the identifier status is set to 41h.
  - If there is no unsent data, the identifier status is set to 40h.
- [(6) Data] places (kc1, kc2) 2-byte data defined by <Function 74> into a single set (key code) and this data set is made into an aligned data group. If the key codes exceed 40 items (80 bytes), they are divided into groups of the upper limit of 80 bytes and then transmitted.
ESC/POS handshake processing is performed for data transmission processing of this function.

[Note]

The host can receive data transmitted from the display only when a Windows PC is connected.
