Serial ports
The server has two standard serial ports: Serial port A and Serial port B. The
operating system can use and share both serial ports; however, the integrated
Advanced System Management processor can use and share only Serial port A.
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.
