1. We shouldn't need to be calling into private methods like `_write`: https://github.com/nioinnovation/python-xbee/blob/master/xbee/tests/test_base.py#L28 2. Are these `_write` tests even necessary? ieee tests use `send` which calls into write so it seems like `_write` is just being tested unnecessarily here.
