If Async is selected, the interface will communicate asynchronously
(using start and stop bits) with the device it is connected to. This mode
of communication is typically used by modems.

If Sync is selected, the interface will communicate synchronously (using
a separate clock) with the device it is connected to. This mode of commu-
