Jef Driesen	c4d3356b6e	Add support for compressed data packets. The new Petrel protocol uses a simple data compression scheme to reduce the transfer times. The data is broken up into blocks of 32 bytes each. Each block except the first is XOR'ed with the previous block, creating large runs of zeros due to the similarity of the data. The zeros are then run-length encoded (RLE) to save space.	2013-04-16 22:26:41 +02:00
Jef Driesen	6f3de69f0d	Move the low-level communication to a common file. This is done in preparation for the implementation of the new Petrel protocol, which shares the low level communication with the existing Predator protocol.	2013-04-16 22:26:41 +02:00

Move the low-level communication to a common file.

This is done in preparation for the implementation of the new Petrel
protocol, which shares the low level communication with the existing
Predator protocol.
