    hallo,

    i'm trying to send some bytes with the uart of a ST6230,but there's problems..i'm receiving nothing

    i have only to send with uart,not to receive so

    uartcr=00000111

    i write:

    ld uartdr,a

    The ST6230 transmits inverted data so you have to connect an external inverter on the UART Tx pin.
