Card-LAN interface
A Dual Port UART handles the functions of the serial ports for the Card-LAN
serial link test port interface. The test interface is an asynchronous 4800 bps
8bit connected to port A of the UART. The card-LAN interface is an
asynchronous 19.2 kbps 9 bit start/stop connected to port B of the UART.
The connection to the test port is available at the backplane/MDF connector.
The signals at this port conform to the EIA RS-232C standard.
