Keyspan:Mini Port Replicator for Mac OS-v2.6 User Manual

The Use INTERRUPT endpoints check box is used to change how the Keyspan adapter communicates with your computer's USB bus. When this option is turned on, the Keyspan adapter will use the INTERRUPT endpoints to communicate with your computer's USB bus. When this option is turned off, the Keyspan adapter will use the BULK method of communicating with your computer's USB bus.

The Port popup menu allows you to select the Keyspan serial port that you want to configure. Please note that each port maintains its own separate settings. As a result you must configure each port individually.

The Port Name text box allows you to change the name of the selected port. Changes will take effect upon reboot. Please note that you cannot change the port name on ports that use the Emulate Modem/Printer Port check box.

The Reset & Close button can be used to recover use of a serial port that is open and and cannot be closed by the application that opened it. When you click on this button, Keyspan Manager will send calls to the port which should reset the port and close it. This will not prove effective in every circumstance.

The Receive FIFO popup menu allows you to configure the number of characters which are stored in the card's "First In First Out" input buffer ("FIFO") before they are made available to the computer. The default value of this parameter is "16". The Receive FIFO improves the reliability of data transfer at high speeds. You can turn this option OFF for performance reasons however this is not necessary in most cases.
