Communication safety
All communications from the Host to the device are verified by:

ID
Checksum: received blocks of data bytes are XORed. A byte containing the computed
XOR of all previous bytes is added to the end of each communication (checksum byte).
By XORing all received bytes, data + checksum, the result at the end of the packet
must be 0x00.
For each command, the host sends a byte and its complement (XOR = 0x00).
ACK = 0x79
NACK = 0x1F
