Serial ports
Your server has two standard serial ports, Serial port A and Serial port B. The
operating system can use both serial ports. A third serial port (system management
port) is only available for the Integrated System Management processor.
Some application programs require specific ports, and some modems function
properly only at certain communication port addresses. You might need to use the
Configuration/Setup Utility program to change communication port address
assignments to prevent or resolve address conflicts.
