Serial ports
Your 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
Netfinity 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.
Viewing or changing the serial-port assignments
To view or change the serial-port assignments:
1. Restart the server and watch the monitor screen.
2. When the message
Press F1 for Configuration/Setup
appears, press F1.
3. From the main menu, select Devices and I/O Ports ; then, press Enter.
Note:
The Devices and I/O Ports choice appears only on the full configuration
menu. If you set two levels of passwords, you must enter the
administrator password to access the full configuration menu.
4. Select the serial port; then, use the arrow keys to advance through the settings
available.
5. Select Save Settings ; then, select Exit Setup to exit from the
Configuration/Setup Utility main menu.
