dlestxetx 1.0.1

DLE/STX/ETX is a packet framing algorithm,
used by some devices (such as Metlink LED passenger information displays)
to transmit data as packets over a serial medium.
This algorithm delimits data using DLE, STX, and ETX control codes.
Packets begin with a DLE STX sequence,
follow with a byte-stuffed data stream
(all DLE bytes in the data are conveyed as DLE DLE),
and end with a DLE ETX sequence.
The dlestxetx module provides functions
to encode data into packets:
>>> from dlestxetx import encode
>>> encode(b'\x01\x10\x05')
b'\x10\x02\x01\x10\x10\x05\x10\x03'
decode packets into data:
>>> from dlestxetx import decode
>>> decode(b'\x10\x02\x01\x10\x10\x05\x10\x03')
b'\x01\x10\x05'
and read packets directly from file objects:
>>> from dlestxetx import read
>>> packets = BytesIO(encode(b'\x04\x05\x06') + encode(b'\x07\x08\x09'))
>>> read(packets)
b'\x04\x05\x06'
>>> read(packets)
b'\x07\x08\x09'
