[Description] The printer sends the available NV user memory.
- ESC/POS Handshaking Protocol is not required for this function.
[Notes] - With this function, the printer sends the "Header to NUL" data shown below:
- The decimal value for the available capacity is converted to ASCII character
data and sent from the most significant digit.
Example:
When 120 bytes is available (not being used), the number 120 is expressed
with 3 bytes of data (Hexadecimal: 31H, 32H, and 30H / decimal numbers
= 49, 50, and 48).
- See previous [Notes for transmission process] for process sending data
group.
(*1) The available capacity indicates the number of bytes not being used.

[Description] Transmits the key code ID for the record stored in the NV user memory.
- ESC/POS Handshaking Protocol is required for this function.
[Notes] - When record exists, the printer sends the "Header to NUL" data as shown
below:
(*1) When the quantity of stored data exceeds 40 records, the printer performs
partial processing, using the following rules:
- If there is unsent data, the identification status of the third byte is
41H or 65 decimal.
- If there is no unsent data, the identification status of the third byte is
40H or 64 decimal.
(*2) The printer performs batch processing when the data to be stored in the
specified record is 40 records or less. At this time, the identification status
of the third byte is 40H or 64 decimal.
(*3) The data is the key code. A terminator is not included in the data.
