[Name]

Transmit the remaining capacity of the NV graphics memory

( pL + pH × 256) = 2 (pL = 2, pH = 0)

m = 48

fn = 3, 51

Transmits the “remaining capacity” of the NV graphics area. The transmission data groups are as indicated in the following table.

Data groups of remaining capacity	Hex	Decimal	Number of data
(1) Header	57h	87	1 byte
(2) Identifier	31h	49	1 byte
(3) Display number	30h - 39h	48 - 57	0–2 bytes
(4) Separator	1Fh	31	1 byte
(5) Remaining capacity	30h - 39h	48 - 57	1–8 bytes
(6) NUL	00h	0	1 byte
