RX / TX Simplex sharing one UART port

Is it possible to have two simplex streams share a single UART port?

For example Rx RC commands and Tx FrSky telemetry.

Yes, standard UART has rx and tx channels. Having RC input and TX from the FC on the same UART is fairly standard in the drone industry. I personally haven’t hooked it up yet, but the docs indicate it shouldn’t be complicated
