It is very easy. You may use RS232 or normal 5V UART. You can choose it depending on the USB to UART converter you are planning to use. If it is having RS232 output, just use MAX232 IC to convert 5V UART to RS232.
You can use softwares like Putty, Hyperterminal, UART Terminal etc. to view the data in a PC.
