If you decide to explore using the jtag_uart, you could try using nios2-terminal, in conjunction with named pipes. It's not a perfect solution, but I think it should work. It should give you the benefits of transferring data at a higher rate, as well.

I know that the following works, from an SDK shell:

nios2-terminal > output.log

and I think (though I've not tested it) that the opposite should also work:

cat input.txt > nios2-terminal

What I'm not sure about is whether or not pipes ["|"] will work or, for that matter, named pipes...in your C code.

It sure would be nice if someone wrote a Windows driver (that looks like a COM port) wrapped around the calls that nios2-terminal is using, huh?
