Examples of Acia6850

com.loomcom.symon.devices.Acia6850
This is a simulation of the Motorola 6850 ACIA, with limited functionality. Interrupts are not supported.
Unlike a 16550 UART, the 6850 ACIA has only one-byte transmit and receive buffers. It is the programmer's responsibility to check the status (full or empty) for transmit and receive buffers before writing / reading.

    private final static int CMD_STAT_REG = 0;
    private final static int DATA_REG = 1;
    
    
    private Acia newAcia() throws Exception {
        Acia acia = new Acia6850(0x0000);
        // by default rate is limited, have it unlimited for testing
        acia.setBaudRate(0);
        return acia;
