Value of al
= low byte of the address
Value of ah
= high byte of the address
Value of cl
= low byte of the count
Value of ch
= high byte of the count
Value of d
= data bytes, from 1 to n
Contains a start address (ah * 256 + al) and count (ch * 256 + cl) of
binary bytes to load into the selected sector, followed by that many
bytes. The start address is relative to the start of the sector. Addresses
run from 0 to 64K.
The printer may return one of several responses. ACK means that the
data was written correctly and the host should transmit the next block.
NAK means that, for some reason, the data was not written correctly.
This could mean that communications failed or that the write to Flash
failed. The alternatives seem to be to retry the block or halt loading and
assume a hardware failure.
