cch
===


 This module allows to encapsulate an arbitrary data-structure, that is
protected by a CRC and then handled further on.


cch_rcv
-------

 Receives tha data-packet and checks for the CRC. If it is OK, then
received' is put to 1, else it is counted down.

Inputs:
	U8

Config:
	*data<void>: NULL
		A pointer to the data to send

	len<int>: 0
		The size in bytes of the data to send


Stats:
	received<int>:
		Status of the received block:
		1 - OK
		0 - nothing
		< 0 - number of consecutive wrong blocks 


cch_send
--------

This module takes a structure, and sends it over the air. Additionally,
it adds a CRC. The reception-part checks for this CRC to be valid.

outputs:
	U8

Config:
	*data<void>: NULL
		A pointer to the data you want to send

	len<int>: NULL
		The length in size of the data to send
