Introduction
The NT8D41BA Quad Serial Data Interface (QSDI) paddle board provides 
four RS-232-C serial ports. These ports allow communication between the

board is normally used to connect the system to the system administration and

background terminal (used in the hotel/motel environment), a modem, or to
