argparse does not provide a good solution when the input arguments should be
different data types. F

The documentation for the io.BufferedRWPair class gives this warning:

Ryan Govostes added the comment:
The origin of this warning involves interleaving read and write operations, and
was added here: https://bugs.python.org/issue12213
I'm not sure if it applies to sockets, pipes, etc. though.
The pySerial documentation advises using io.BufferedRWPair
Ryan Govostes added the comment:
This absolutely should be documented. If adding an earlier event is not
