UART_Send CMSIS2 problem

Hi my friends.

I'm trying to write on UART0 using the command UART_Send (implementation by CMSIS 2.0) but I'm get wrong characters on PC terminal.
When I use UART_SendByte command, I have no problem. The byte arrive ok.
Look inside UART_Send implementation, I verify that this method call UART_SendByte, so why it doesn't work?
I'm using ETT Chinese Kit with LPC1768, CMSIS 2.0 on Linux and Code Sorcery.
I get the same error when I tried to run CMSIS UART examples.

Here the code. (I dont post .h because calls only CMSIS headers)

#include "gps.h"

void ConfigGPS_UART()
{
    /* UART0 */
    UART_CFG_Type UARTConfigStruct;
    UART_FIFO_CFG_Type UARTFIFOConfigStruct;
    PINSEL_CFG_Type PinselConfig;

    PinselConfig.Funcnum = PINSEL_FUNC_1;
    PinselConfig.OpenDrain = 0;
    PinselConfig.Pinmode = PINSEL_PINMODE_NORMAL;
    PinselConfig.Pinnum = PINSEL_PIN_3;
    PinselConfig.Portnum = PINSEL_PORT_0;
    PINSEL_ConfigPin(&PinselConfig);        // RXD0 -> P0.3
    PinselConfig.Pinnum = PINSEL_PIN_2;
    PINSEL_ConfigPin(&PinselConfig);        // TXD0 -> P0.2

    UARTConfigStruct.Baud_rate = 9600;
    UARTConfigStruct.Databits = UART_DATABIT_8;
    UARTConfigStruct.Parity = UART_PARITY_NONE;
    UARTConfigStruct.Stopbits = UART_STOPBIT_1;
    UART_Init(LPC_UART0, &UARTConfigStruct);

    UART_FIFOConfigStructInit(&UARTFIFOConfigStruct);
    UART_FIFOConfig(LPC_UART0, &UARTFIFOConfigStruct);

    UART_TxCmd(LPC_UART0, ENABLE);
}

Here the main.c

#include "main.h"
#include "led.h"
#include "gps.h"
#include "lpc17xx_uart.h"

uint8_t msg_test[] = "NXP LPC1768 UART OK\n\r";

You allrigth Zero.
Sory, I made a mistake. I post on wrong forum. But I have the LPC-Link and I will to do the same test.
I post the result later.
