'bytearray' object has no attribute 'encode'

[WaltzKing]

Trying to run msp430.bsl5.uart and getting the error "'bytearray' object has no attribute 'encode'". This is with Python 2.7.12. Is this a Python2 vs. Python3 issue?

C:\work>python -m msp430.bsl5.uart -p com11 -v testhex3.txt Debug is False Verbosity level set to 2 Python version: 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (Intel)] pySerial version: 3.4 action list: program_file() reset() Programming...

I do not believe this is a Python2 vs Python3 issue. I see the same failure in Python 3.6. The error message has changed slightly to: "AttributeError: 'bytes' object has no attribute 'encode'"
