Infra-red data port

A data port that uses infra-red data association (irDA) as the standard for wireless communications between computer and mobile phone devices. For example, to update the phone list on your irDA-enabled PC, you would line up the infra-red ports on each device and then transfer the phone information to your PC. This is a wireless transfer, so you don't need a cable or extra software. (Ericsson)
