    It's an excellent tutorial as well as an interrupt driven full-duplex software UART. The code is quite simple and easy to follow.
    Hi,

    Full-duplex software UART is not possible or possible only if the baud rate
    is very low and interrupts are used. (Software UARTs use bit-banging).

    Soft Uart for P12 by Warren Schroeder:

    If you look at the code you will see that RX uses an interrupt and that in
    the SUB TX_19200 interrupts are disabled. This means that while
    you are sending data you cannot receive data at the same time. (Not Full-duplex).

    Best regards,

    Luciano
