The MC68681 and MC68692 dual asynchronous receiver/transmitter (DUART) component provides two serial ports, as well as a 16-bit programmable counter/timer.
dart driver provides support for the
two serial ports found on board all AViiON systems.
dart serial ports have a two character
buffer on the transmit path, and a four character buffer on the receive
The following link speeds are supported by the
dart driver: 50, 75, 110, 134.5, 150, 200, 300, 600,
1050, 1200, 1800, 200, 2400, 4800, 7200, 9600, 19200 and 38400 bps.
