    "But whatever you do, the UART is always [full] duplex, even if the specific connection may make the full system being half duplex."

    Even with a a hardware connection capapble of full-duplex (ie, completely separate transmit & receive paths), you might use a half-duplex software protocol over the link.

    eg, XMODEM will not transmit its next packet until the previous one has been acknowledged...
