If you want use NIOS IDE terminal you need to configure it to connect to particular RS232 port. Choose RUN->RUN->Target Connection there is NIOS II Terminal Communication device.

If you use multiple processor you cannot use JTAG-UART. Thus you should use physical ports and need to connect it to computer and using above description connect NIOS II terminal. Moreover this is not enough, go to your software project select it and with right click of the mouse choose System Library Properties. There is three points: Stdout, Stdin, Stderr and choose UART in windows near these description. It points printf() to your UART.

If I understood your problem correctly it should help.
