Or a combination of the two...

cat <filename> | nios2-terminal >& terminal.log

You could write more elaborate scripts/code using pipes going into and out of nios2-terminal.

The above is OK if batch style IO is acceptable.

Do you know if it is possible to use the IO redirection tricks above to allow an existing windows terminal app to talk (tx and rx) over the jtag uart?

The all the redirection examples I have seen, the data flow is one-way only.

I am thinking that you would need something like a virtual serial port.
