hyper terminal does not show some character send 48 ascii of 0 or asciis of 0 to 9,a to z. then check it will be working if not then i think there will be ur h/w problem for h/w checking short tx, rx pins and check wheter data recieved
my crystal is 11.0592 according to calculation it get divided by 4 and uart ckt by 16so value comes 172800 which is divided by 9600 so it comes 18 so 18-1 =17 i put that but still not working
the best test is short the tx rx pin and then test keboard if ur echo is comming means pc recieving pin is working then write code in this way that when u get data from pc then retransmit to pc
