UART, easy prob.

hi everyone

im using 2811,,,,the problem,is im trying to receive and send the same char
8-bit .from other processor

Uint16 Rx_UART, Tx_UART;

//Transmit&Receive
while ( ScibRegs.SCIFFRX.bit.RXFIFST != 0 ) {

Rx_UART = ScibRegs.SCIRXBUF.all;

Tx_UART = Rx_UART;
}

while (ScibRegs.SCIFFTX.bit.TXFFST != 0);
ScibRegs.SCITXBUF = Tx_UART;
SciaRegs.SCIFFRX.bit.RXFFOVRCLR=1; // Clear Overflow flag

its not working,,,,im sure about the baud rate,,,,,,

in the other processor,,,,i keep sending the same value,,,over and over Start a New Thread

i think the baud rate is right,,,,because its working fine if i hashed the
condition of the receiving,,,while (ScibRegs.SCIFFTX.bit.TXFFST != 0);

also if you familiar with 97J60 controller,,,,its working only when i hash
the condition of the receiving,,,, the interrupt flag,,,,like here,,,
////////
while(!DataRdyUART());
c = ReadUART();
//////////////

// working only when i hash while(!DataRdyUART());,,,although its suppose to
be before Read instruction,,,,, so strange, i dont know why,,,,

the HW connection is cross,
Tx->Rx
Rx->Tx
just two pins connected

any help will be highly appreciated,,,
