# Copyright 2017 Krystian Struzik <toner_82@tlen.pl>

# Based on Ron Wellsted driver for Wouxun KG-UV8D.

# KG-UV8D Plus model has all serial data encrypted.

# Figured out how the data is encrypted and implement

# serial data encryption and decryption functions.

# The algorithm of decryption works like this:

# - the first byte of data stream is XOR by const 57h

# - each next byte is encoded by previous byte using the XOR

# including the checksum (e.g data[i - 1] xor data[i])

# I also changed the data structure to fit radio memory

# and implement set_settings function.
