You will need to rewrite putchar() to use the other port.It's in putchar.c - surprise! See Chapter 6, "Advanced Programming Techniques" in the manual. Similarly getkey() for input |

RE: Then what about interrupt mode? L T
Since polled I/O consumes too much of the processor's computing power, can I find some example using buffered interrupt instead?

Search the Keil support site - there's certainly a C51 interrupt-driven example there!

You need to write your own copy of getkey, and putchar to redirect the printf to the desired I/O port. The c166 toolchain includes a sample for you to modify. By the way they are polled I/O.
