Assigning the Interface and Data Format
The RS-232 standard specifies several different data drivers for the PowerMac computer.
The Media Server can send commands using any of these drivers. Check the USB to
Serial device’s documentation to determine the driver used by your serial device, then set
the interface using this procedure:
1. In the Catalyst Control window’s Custom Serial panel, click the field labeled No
Output to bring up a pop-up menu.
2. When an RS-232 device is attached to one of the PowerMac USB ports, its driver
appears in this pop-up menu. By default the menu also includes several PowerMac
system options:

commands over MIDI.
Apple IAC Device IAC Driver IAC Bus 1. The Inter-Application Communications
