My application require two UART's, so I am using NXP's 89c669...i am able to receive data (Rx) but unable to send data on the same port(Tx)...can any one give me a solution..or a example program to send & receive odata on same port of 89C669...
Thanks
RS-232? RS-485? TTL? what?
"Hello World" is widely available and probably the simplest example of sending...
