All messages and data are transferred through this 512 KB dual-ported memory.
The buffer area appears as normal 16-bit memory to the PC AT I/O channel.

UART 16C550C
The UART chip,
16C550C
, is an intelligent asynchronous controller capable of
supporting one full duplex channel that transfers data at
921.6 Kbps
simultaneously.
To increase the overall data throughput, special features such as on-chip FIFO and
on-chip hardware flow control are used to reduce the number of interrupts to the on
board CPU and to prevent any loss of valuable data.
