NAME
       duart - Dual Asynchronous Receiver/Transmitter

DESCRIPTION
       Each Aviion system will have one or more duart serial controllers.
       Each duart serial controller will support up to two asynchronous
       serial ports. Built-in serial ports are supported by a duart serial
       controller, but serial ports that are attached via an expansion bus
       are not supported by a duart serial controller.

       Duart supported serial ports present the standard DG/UX terminal
       interface described in termio(7).

       The termio structure c_cflags options B50, B200, B34800, and EXTB are
       not available.
