# = ASCII pound character (0x23)

n = ASCII decimal digit ranging from 1 to 9. This value specifies the

number of digit elements, d..d, that follow.

d..d = ASCII decimal integer that specifies the number of data words that

follow.

(DAW) = Data Word. Two 8-bit data bytes, low byte followed by high byte.

The data is transmitted in a row and column sequence beginning at the display’s upper left-hand

corner, proceeding row by row and ending at the lower right-hand corner.

The following example describes how the host controller requests the current frame and receives

the data. The received data frame has the dimensions of 64 X 60. Therefore, the LBA-PC

transmits 3840 data words (pixels), or 7680 bytes to the host controller.

The following example describes how the host controller requests and receives data in frame

number 17. The LBA-PC sends the 32 X 30 frame as 960 data words or 1920 bytes.
