Asynchronous serial interface is generally used as dialing port and connected to a
modem or a Terminal Adapter (TA). In this case, regardless of the operating mode of
the device, only an appropriate baud rate for the interface needs to be selected.
Serial interface is generally used for the direct connection to such a device as DDN,
frame relay, or X.25 switch.
