You can use putc to send and getc to receive any character from 0x00 to 0xFF over a serial port. Same with pc.putc to send data to the PC.

I think the putc() can handle the binary data.
For just in case, I tried next code on mbed LPC1768.

It seems the output is fine. 

#include "mbed.h"

Serial  serial( p28, p27 );

int main() {
    char    c   = 0;
    
    while( 1 ) {
        serial.putc( c++ );
    }
}
