os.system doesn't report if any of the commands fail. This means that if
something goes wrong it happily reports success making it hard to debug
issues.

This reduces logic a bit. It does not make large difference on usual design with
only 1 UART, but is interesting on designs with hundreds of UARTs used to "document"
FPGA boards :) (similar to https://github.com/enjoy-digital/camlink_4k/blob/master/ios_stream.py )
