SerialPC & Serial Question?

Hi, I use LPC11U24. I trying follow code. In PC terminal, can print out some string. However, I use a logic analyzer to measure LPC11U24:pin9, will have the same serial string output. But, I did not declare it (pin9) is serial output. This problem which will not be a bug?

Provide a serial pass-through between the PC

#include "mbed.h"
 
Serial pc(USBTX, USBRX); // tx, rx
 
int main() {
    while(!pc.writeable());
    pc.printf("Echoes back to the screen anything you type\n");
    while(1) {
        pc.putc(pc.getc());
    }
}

Hello Lin-Ying Lee,

the handbook for your board: http://mbed.org/handbook/mbed-NXP-LPC11U24

Serial pins are also wired to the p9 and p10 according to the picture.
