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.
