Example UART1 is not giving output

"I have opened this Keil example problem UART1.c ...with Aduc7026"

What example is that?
Where did it come from?
Is it supposed to work with the Aduc7026?

From keil code examples

C:\ADuC_Beta702x\Code\Keil Code Examples\UART\UART1

#include <ADuC7026.h>

extern int write (int file, char * ptr, int len); // Functions used to
extern int getchar (void); // to output data
extern int putchar(int); // Write character to Serial Port


int main (void) {
unsigned char jchar = 0x30;

char output1[13] = "Hello World\n";

// Setup tx & rx pins on P1.0 and P1.1
GP1CON = 0x011;

// Start setting up UART at 9600bps
COMCON0 = 0x080; // Setting DLAB
COMDIV0 = 0x093; // Setting DIV0 and DIV1 to DL calculated
COMDIV1 = 0x000;
COMCON0 = 0x007; // Clearing DLAB

GP4DAT = 0x04000000; // P4.2 configured as an output. LED is turned on

while(1)
{

GP4DAT ^= 0x00040000; // Complement P4.2
write(0,output1,13); // Output Data
jchar = getchar(); // RX Data, Single Byte
write(0,&jchar,1); // Output Rxed Data
}
}

so this one is the program which isnt giving any output.

Thanks
