Format

The format is packet based. The packet is somposed of an 0x01 byte, the packet payload size (4 bytes, big‐endian), the packet address size (4 bytes, big‐endian), the packet data, and a one‐byte simple sum of the payload data.

If the packet payload is more than 1024 bytes, there is an intermediate checksum after each 1024th payload pyte.

The end of file is indicated by a packet with a zero‐length payload.

Command Line Option

Size Multiplier

In general, binary data will expand in sized by approximately 1.002 times when represented with this format (worse if there are many short data regions).
