I think a synch BYTE (Start of Packet Byte) is too small to be useful. =
One
could reasonably expect to encounter 0x25 every 256 bytes, on average, =
in a
binary PDL file. Why not a synch WORD or DWORD, say 0x3f2c59d1? You'd=
only
see that randomly every 4 GB or so. The additional 3 bytes would be
insignificant compared to IPP's verbosity.
What does an acknowledgment (ACK) look like? Is there such a thing as =
a NACK?
What happens if a required ACK is not received? Retries?
How many packet length bytes are there? Is there any restriction on pa=
cket
size?
