See Hello World with System.out to understand how to configure one of the available serial interfaces and direct your standard output onto this stream. On the host side you have to determine which port number your operating system has assigned to the port. Open any terminal program, such as Putty, Hyperterminal or Realterm. Configure the port setting similar to the target setting and open the connection.
The Freescale MPC555 offers two independent serial interfaces with RS232 Protocol, SCI1 and SCI2. When using our NTB MPC555 Headerboard, the SCI1 is connected through the USB Background Debugging Interface (USB-BDI) to the host where it will be visible as a virtual COM port. The SCI2 can be connected with a standard serial cable (DB9 connector).
The Freescale MPC5200 has six built in Programmable Serial Controllers (PSC), which can all work as UART's running the RS232 protocol. Check your hardware manual to see which of the PSC can be used on your board.
