Assignments:

illustration of these ports, see “Input/Output Connectors” on
page 91.
Select Serial Port to view or change serial and infrared
port assignments.
Software recognizes ports from their port assignments.
Each serial port must have a unique serial-port
assignment. The Configuration/Setup utility program
assigns serial ports, but you might have special hardware
or software that requires you to change these
assignments.
You can add serial ports by installing a serial adapter in an
expansion slot. See the documentation that comes with
the serial adapter for information about port assignments.

the infrared connector. This enables you to transfer data to
and from other infrared-capable computers or printers.

B/infrared port. When switch 7 is set to ON, serial
port B or the infrared port can be selected using the
