Why assembly? Almost everyone uses C. Nios dev tools provide the driver for the rs232 module with the basic functions to send/receive data.

Browse the forum and Altera website: you'll find a lot of code samples.

On the PC side the simplest solution is using Hyperterminal or a similar program to send commands and receive answers with a ASCII protocol.

If you need something more complex, like file transfer, you must write a specific client program which manages serial port data according to your needs.
