/* Transmit String through UART TX Line */
UART_UartPutString("CY8CKIT-042 USB-UART");
for(;;)
{
/* Get received character or zero if nothing has been received yet
*/
ch = UART_UartGetChar();
if(0u != ch)
{
/* Send the data through UART. This functions is blocking and waits until

UART_UartPutChar(ch);
}
}
