    I am trying to use both UART (Upsd3234A-40). Uart 0 work fine but Uart 1 is not working. I am using UPSD_UART.C/.H from DK3200_DD directory.

    -------------------------------------------------------------

    // UART0...Works

    upsd_init_serial(0x54,uPSD_UART_Timer(0, 9600, 2)) ;

    EA = 1 ;

    uPSD_UART_Putchar('8',0) ;

    -------------------------------------------------------------

    // UART1...Not working

    upsd_init_serial(0x55,uPSD_UART_Timer(1, 9600, 2)) ;

    EA = 1 ;

    uPSD_UART_Putchar('8',1) ;

    --------------------------------------------------------------

    Just found the problem in upsd_uart.c.

    upsd_init_serial() PCON was set to 0xC0 instead of 0x0C (RCLK1/TCLK1).
