Add some circuitry to switch between using the parallel port for
downloading and a RS232 buffer connected to the standard serial
port. Writing a software UART device that can be used with software
expecting to talk via a UART would be far to much work for very little
advantage.

Perhaps because the ISP protocol is synchronous?

What the parallel port, for Pete's sake? The serial port should have
been by far the more obvious choice, and easier to use, too --- just
run a terminal program like good old Kermit and *see* what comes out
of that port, without any hassles.

I am programming the ATMEGA128 using the parallel port of my PC. The pins
from the programmer go to the UART RX / TX of the MCU for downloading the
program. I want to send debug info from the MCU to the PC using the same
UART. I have code with me to send data using this UART .
