Using Your Computer 51
Infrared (IrDA)
Because your PowerBook is equipped with infrared (IR), you can exchange files and data
without using wires. The type of IR used is the industry-standard IR communication method
known as IrDA.
You can use infrared to share files with another IrDA-equipped computer, communicate with
other infrared devices such as handheld organizers, connect to an infrared network, and
even print on an infrared printer. Sharing files using infrared is the same as sharing files using
Ethernet, except that AppleTalk and TCP/IP are set to Infrared instead of Ethernet. File
sharing and IrDA printing are not supported in Mac OS X.
Note: You cannot share files with a computer that only supports IRTalk (a non-standard IR
communication method used by some older computers).
Making an Infrared Connection
To connect to another computer using infrared:
1 Position the IR windows of the two computers so that they are directly facing and within one
meter of each other.
2 Configure AppleTalk and TCP/IP to communicate using infrared.
3 Make sure that file sharing is turned on in the File Sharing control panel in Mac OS 9.
For More Information on Infrared
Information on configuring the Mac OS to communicate using infrared and setting up file
sharing is available in Mac Help (see page 42). Choose Mac Help from the Help menu and
search for “infrared” or “file sharing.”
