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

(in a there's my byte), then i wait until txty is set but nothing...

my uart is connected with com1 of my pc, i haven't got the development kit

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